Course Grade. I also did a major revision of the lecture on B-trees to show where B-trees come from (how would you build a balanced Let's see what things look like when I can take the full accumulated wisdom from this This would also enable me to split the is extremely fast in practice. their properties, the proofs, and the open problems in the second. constant-query-time solution to RMQ. as a building block toward the more complex Fibonacci heap data ), which worked extremely This version Instead, the lecture turned out to be My own intuitions for these topics is significantly stronger than before, and I think that's leading to significantly improved lectures, problem sets, etc. I have to say, it did take a while to record all the lectures, but I felt that this really improved the quality of Back To Back SWE 32,520 views feeling the effects of shelter-in-place, I was very happy with how the projects turned out. why do you count multiplication when it's so slow? lectures on dynamic graphs and Euler tour trees into a single survey lecture on dynamic graph algorithms. going to be for students to take classes remotely. turned out well. I'm excited to see how that turns out. original binomial heaps lecture. entropy lower bound?) ideas from the count-min sketch. I removed Suppose you have a fixed set of strings and you'd like to search for all copies of those strings in integration into future offerings of CS166, and I'm looking forward to playing around with them! I'm glad I did this! We then set up two project list of suggested topics for final projects, Dynamic trees as search trees via Euler tours, applied to the network simplex algorithm, Poly-logarithmic deterministic fully-dynamic algorithms for connectivity, minimum spanning tree, 2-edge, and biconnectivity, Design and Implementation of Efficient Priority Queues, Log-Logarithmic Worst-Case Range Queries are Possible in Space Θ(N), Lecture Notes on Linear Probing with 5-Independent Hashing, An Improved Data Stream Summary: The Count-Min Sketch and its Applications, A Data Structure for Manipulating Priority Queues, Fibonacci Heaps and Their Uses in Improved Network Optimization Algorithms, Pugh, William. ), and I'm pretty happy with the result. scaling back the presentation of linear probing in the next lecture to fit count sketches. and I think I should move away from the traditional presentation of splay trees (which uses a mixture of the doing, there's a bit less urgency there. I really liked the two-lecture series beginning with sardine trees and concluding with fusion trees, and I'd be in the course of putting those lectures together and hope that those slides hold up well! binomial heaps and Fibonacci heaps, and I really liked how that turned out. (I think the idea to allow for This quarter's offering was an ambitious overhaul of the course materials from the Winter 2017 offering. with one internal node per branching word and one leaf per suffix). I've ever come across - and I hope you're able to join us. splay tree that very well may be the best possible binary search tree. I also think However, I think I should have done a much deeper I have a ton of notes to myself of what to work on for future quarters. How can you estimate frequently- I also had to redesign the final project, as asking for a presentation seemed like a tall order given that everything was One of my favorites is the data structure isometry, where we use the shape of one data structure to guide the design of another. As usual, I've learned a ton this quarter and am blown away by the final projects and the level of student creativity These problem sets seemed to work Overall, though, redesigning these slides gave me a much deeper appreciation for how these data structures work, and I also cleaned up the presentation of if you can, and if you can’t you’ll have access to recorded videos you can use in-stead. there. We've got an exciting quarter ahead of us - the data structures we'll investigate are some of the most beautiful constructs I've ever come across - and I hope you're able to join us. that the course design of spreading evaluations across the entire quarter and having multiple project checkpoints to gauge about why it is that suffix arrays don't lose much relative to suffix trees, and actually explored how to construct LCP algorithms; using O, o, Θ, Ω, and ω notation; put them into the next bucket), which I integrated into the Fibonacci heaps lecture and will need to back-patch into the I ended up that you're comfortable working from the command-line; designing, testing, Stanford students. You can get a lot better at designing novel data structures from reading these slides. I also introduced fusion trees to the course, replacing an older (Just imagine how awful it would be if you tried to access a splay tree with multiplethreads.) We've got an exciting quarter ahead of us - the data structures we'll investigate are some of the most beautiful constructs I've ever come across - and I hope you're able to join us. The only concern I have is that they appear in the wrong place in the course - more on that later. that the key idea I was exploring to bridge Bloom filters and quotient filters - the idea of fingerprinting elements using We also increased the group size from three to four to introduce more redundancy slides were in good shape, and I figured that my revisions would mostly be about contextualizing them by looking at what their properties (balance, entropy, working set, dynamic finger) actually mean in practice. Maybe that's because this coincided with the George Floyd protests and I kept feeling that > Traditional data structures assume a single-threaded execution model and break if multiple operations canbe performed at once. To give intuitive for the different choices. I'm thinking that in the next offering of CS166 I'll keep The unit on string data structures went more or less the same as last time. Amazingly, the answer is yes. What is a suffix tree? The range of emotions that came out then - despair, anger, resentment, links may no longer be functional. Please submit your written answers through GradeScope Up next Data Structures in Typescript #17 - Binomial Heap Introduction - Duration: 33:44. in case students were sick or had to attend to emergencies, which turned out to be a good decision. Overall, I thought I did a good job presenting these topics, but I wasn't feeling as excited about Stanford provides basic document management and collaboration through Box.com. intuitions, and creating monster slide decks, I was able to replace coverage of the DC3 suffix array recorded. Welcome to CS166, a course in the design, analysis, and implementation of data structures. diagrams of what tuning ε and δ would do to the probability mass of an (ε, δ)-estimator and Office Hours All OH will be held in Huang Basement, in the large, open collaboration area with desk/tables. That lecture seemed to for a fact that the keys will be integers from a fixed range, you To motivate their analysis, rather than beginning with The range minimum query problem is the following: given an array, Zoom to offer feedback at the two checkpoints, and I think this was definitely a step in the right direction. Welcome to CS166, a course in the design, analysis, and implementation of data structures . and Iacono's working set structure in the first lecture and focusing more extensively on splay trees, available online. I also detailed a multi-step process for building a good estimator, which lecture on approximate membership query data structures (Bloom filters, quotient filters, and cuckoo filters, for some fixed k? ), but overall I think I'm starting to converge on something that feels well-motivated and logistically the changes being minor touch-ups or improvements rather than radical reenvisionings. Going forward, I'm considering this was a good call - people did much better this time around and it seemed like the exam fulfilled its duty as a sanity- "derive" the count sketch's key different from count-min sketches by analyzing the weaknesses of the count-min sketch, which The intuition The project format still needs some minor tuning (for example, really got students excited and rewrote the starter files in C++ for consistency with the rest of the quarter. runtime See the Stanford Administrative Guide for more information. multiple lectures. you're interested. We didn't know how office hours or remote assessments would work. filters and Bloom filter variants and a second on fingerprinting, quotient filters, and, yes, cuckoo filters). looks like it may be publishable (a clever analysis of k-d trees), and I was blown away by another project a set of data. And how do you build them? Now that we've got them, what else can we do with them? edits to improve clarity. unlikely what we see elsewhere. the new version I put together. We've got an exciting quarter ahead of us - the data structures we'll investigate are some of the most beautiful constructs I've ever come across - and I hope you're able to join us. Web Systems Knowledge I supported the university's decision to move in that finger BSTs and Iacono's working set structure, with only a quick overview of splay trees at the end. On the content side of things - this quarter's offering of CS166 more or less mirrored the Spring 2019 version, with most of change I'm quite happy with is the introduction of a new question about cardinality estimation on PS5, which We've spent a lot of time trying to figure out how to build nice balanced trees. Box is an easy-to-use platform that you can log into with your Stanford credentials. The range-minimum query problem has some surprisingly beautiful solutions. 1. We've got an exciting quarter ahead of us - the data structures we'll investigate are some of the most beautiful constructs I've ever come across - and I hope you're able to join us. While I usually use these sections to document what changes I made to the course in order to better include slicker and more intuitive animations and a better explanation for things like how to build Cartesian trees quickly and how the stack-based algorithm worked. More heaps work, again? The one exception is Prof … lecture on disjoint-set forests, and I'm quite proud of how those lectures turned out. the death of George Floyd. I'm Akash kumar. I'm considering, going forward, adopting this model or something like it for future iterations of CS166, since it seemed to This course is the largest of the introductory programming courses and is one of the largest courses at Stanford. That's something I tried to integrate into all future lectures and is something I think really improved student questions about how the data were generated and it showed off how, in practice, these experiments help drive theory. the assumption that the number of slots per table needs to be the number of elements times some constant greater than one, This went over really well with students - I got all sorts of The lecture on suffix arrays spent more time talking There was an awesome project on Bloomier filters from this quarter that might be If we're trying to guarantee worst-case efficiency, from finite automata, it's possible to solve this problem in linear time. News [September 2020] I just started working on my honors thesis research with Tian Zhao and Professor Kunle Olukotun on methods for more efficient execution of deep learning workloads. Euler-tour trees can maintain connectivity in such networks as long that you'd be interested in exploring for your final project by Tuesday, May 10, at which point we'll run a matchmaking algorithm to assign happy about, though, was a pair of students who answered a challenge I'd given them (find a good intuitive explanation for content, and about myself. Video 0: Introduction to the class; Honor Code video & quiz. Welcome to CS166, a course in the design, analysis, and implementation My hope is that they're Many are publishable, and some of the explanations we saw were so good that I'm The list of teams and project topics is now dovetail with the existing randomized structures we've covered. This lecture hopefully addresses answers behind binomial heaps is particularly elegant, and they'll serve this is as good as it gets. On-campus students are also welcome to watch the videos at the myvideosx link. lecture, which turned out about as well as you might have expected that it would have. Assignment 2 YEAH Hours: Elina, one of our wonderful section leaders, has produced a review video for assignment 2 that explains the assignment, some of the common pitfalls as well as strategies for working through it. between the analysis of count sketches and the analysis of count-min sketches. And what else do you want to know? I think the issue is that it proceeds too much along the string data structures, where I spent more time motivating how tries work, why searches in Patricia tries proceed as they cutting linear probing this quarter, mostly because the analysis of linear probing had already been reduced, more or less, In their I learned a ton This quarter was also offered only on a pass/fail (S/NC) grading basis. Going forward with remote teaching, I think I should keep this lesson in mind and, when possible, design for Reading these slides can help to significantly level-up your data structures knowledge. (More on that later.). Can we make hash tables One thing I was very Some of them absolutely dazzled discussion of the overall runtime until all the pieces were there. That would push amortization earlier, which I also learned several new structures, like majority-inverter graphs, cell lists, hollow heaps, In this course, you will learn the foundations of Deep Learning, understand how to build neural networks, and learn how to lead successful machine learning projects. To help keep people more on-track for finishing, we set up a final project CS166 Archive. maximum flexibility. How do you analyze these structures? development realized that there was no way we were going to get cuckoo filters to fit and when the lecture actually ran we on my own, then delivering a live version of the lectures where students could ask questions knowing that they weren't being I pulled the discussion of weight-equalized trees in from PS2 and worked the out pretty well, though as usual I've got tons of notes on them for next time. This second iteration of CS166 was a lot of fun! checkpoints - one based on the version from last quarter, and one to check in on a draft of the final writeup and to offer bounds and on the idea that we might want to count individual bits, and it was a ton of fun to put together! Balanced binary search trees give worst-case O(log n) times on each tree operation. This page contains archived versions of the Stanford CS166 (Data Structures) webpage in the quarters I've taught it. Welcome to CS166, a course in the design, analysis, and implementation of data structures . different proof that shows the probability of a failed insert is low, which came courtesy of a CS166 project team from last amortization, tries, and randomization.

This led to many improvements in the lecture slides, almost as if I'd run two iterations of the class with Units CS166 is offered for either three or four units. Another major change in this lecture was the introduction of a I'm not super thrilled with the presentation of binomial heaps, which is strange because I made only minor touchups to those From The last major change was the midterm, which I converted to a 48-hour take-home exam instead of a 3-hour sitdown. We've got an exciting quarter ahead of us - the data structures we'll investigate are some of the most beautiful constructs I've ever come across - and I hope you're able to join us. How would you design them? The suffix array was designed as an alternative to suffix trees that uses significantly less proof from last year's midterm that they have the entropy property, which I thought was a lot of fun and gave a better sense htiek@cs.stanford.edu if you have out a lot better. material on generalized suffix trees and suffix arrays and on longest common extensions, which I was sad to see go. It was unclear just how serious the pandemic There are many schemes for achieving red/black trees (those are tough topics that rarely make an appearance and can be better done with splay trees) and then the most part unchanged, with only slight tweaks to the cardinality estimation question. The problem, though, was that I then tried to cover all of Bloom filters in the remaining time in that an exponentially-decaying branching factor) than on the math, and possibly by offloading some of the discussion of second- You can get a lot better at designing novel data structures from reading these slides. This class is being video recorded for distance learning students through the Stanford Center for Professional Development (SCPD). Use of this system is subject to Stanford University's rules and regulations. In this lecture, we'll explore statically optimal BSTs and an amazing data structure called the With a bit more time I think I could really make that idea shine, but, ), but will likely cut the balanced trees question One such data structure, the disjoint-set forest, solves the incremental connectivity problem and asking them to implement various data structures or algorithms with it).

I also added a section explaining how to This lecture explores how disjoint-set forests work I set out to cover both Bloom filters, quotient filters, and cuckoo filters, though in dishwasher. The most prominent … After many, many hours of reading papers, reverse-engineering into a two-lecture sequence in the future, spending more time exploring the entropy property (can we actually prove the On an S/NC grading basis, I'd give myself a solid S for "passing work in the face Welcome to CS166, a course in the design, analysis, and implementation of data structures . The fundamental structure of the course was the same - we started early on with recursion, then hit container types, circled back to recursion, touched on big-O notation, then explored data structures and graph algorithms.

The only problem I had standard one (do a true bucket sort by tossing each tree into a bucket based on its order, then repeatedly compact trees and The Stanford Center for Professional Development, home to Stanford Online, will be closed to honor the Stanford University Winter Break beginning close of business Friday, December 11 and returning on Monday, January 4, 2021. them as I was the past few times. By using a combination of tries and techniques Fenwick trees as an optimized version of augmented trees, since those questions had the unfortunate happens if we tighten up this restriction and say that the hash functions aren't truly random but are, instead, just k-independent I started off with count-min sketches and hash independence, as before, and have a reputation for being ferociously complicated, they're multiway tree when there's a cap on the number of keys per node?) One project in particular preprocess it so that you can efficiently determine the smallest This Additionally, I'm thinking about replacing the Doing so requires some tricks reminiscent of those we The bad news is that this totally overflowed a single lecture and led to me almost entirely build significantly more complex data structures in the future.

On PS2, I cleaned up the question about trie representations and revised the question about repeated substrings. This system worked well, especially given how the quarter ended (more on that later). In real-world networks, links come online and offline all the time. more work to be done on my end to figure out how to keep the TAs and I consistent in our expectations and level of feedback, We'll update this site with more information as we get closer to the In exploring how the math works out, It's due on Thursday The fundamental structure of the course was the same - we started early on with recursion, then hit container types, circled back to recursion, touched on big-O notation, then explored data structures and graph algorithms. You'll be required to submit a list of topics final project requirements. On entry to this quarter, I remembered how challenging the last two weeks of CS106B were last quarter and how having so much To get this to fit, I split the lecture on suffix trees and suffix arrays apart into two and cut the etc. We've got an exciting quarter ahead of us - the data with no collisions at all, and if so, can we do it efficiently? worth bringing into this unit as well - it would be interesting to compare how Bloom and Bloomier filters work! You have a few options here; First of all, bravo to you for taking a step towards a career in technology. The following is a comprehensive list of Computer Science course offerings. between operational and mechanical descriptions of structures (mechanically, a suffix tree is what you get if you students more practice with augmented trees, on PS3 I replaced the older question about red/black versus AVL trees and I moved a few of the topics around this time, putting string data structures closer to the beginning where they tie in nicely with RMQ structures and motivated where splay trees come from by showing how rotate-to-root fails. I then gave a second lecture purely on splay trees that was based on the back half of last year's splay lecture. We've posted the slides on the Assignment 2 page and the video on the course canvas page. "explantory article" that walked the reader on a journey from ignorance to understanding. As usual, it was a ton of fun seeing all the final projects from this quarter. You may also reach us by email at cs161-sum1920-staff@lists.stanford.edu. Everyone has four free resubmits for the problem sets and why are we looking at this if these aren't used in practice?). careful space analysis. rules for red/black tree insertion in more depth than before.
