Advanced Algorithms (COMPSCI 224), Lecture 1
Harvard University・2 minutes read
The CS224 Advanced Algorithms course led by Gelani Nelson and TF Jeffrey includes scribing, psets, and a final project, with key components due on specific dates and submission guidelines outlined on the course website. The course delves into various data structures and sorting algorithms, exploring topics like the Word RAM model, Van Emde Boas data structures, and efficient predecessor queries to optimize time and space complexities in algorithm design.
Insights
- Faster sorting algorithms exist beyond n root log n, such as o of n log log n deterministic and o of n square root log log n expected time randomized, with the pursuit of a linear time sorting algorithm still an open question.
- The VB tree data structure offers o of log log U time complexity for predecessor and insertion operations, utilizing hash tables for cluster IDs and pointers to non-empty clusters, ensuring linear space complexity through efficient storage and charging of minimum elements.
