COL 702: Advanced data structures and Algorithms

Semester I 2017-2018

Instructor : Sandeep Sen

Lectures: M,Th 8 - 9:20 , Venue IIA 101

Office hours: Mon 9:30a - 10:30a

Teaching Assistants:

The total will be computed as Minors 1 and 2 - 20% each, Major 40%, Quizes - and assignments - 20%.
Two of the best quizes (out of three) will constitute 5% and the rest from the programming and take-home assignments.

Attendence policy Students should abide by the attendence rules stipulated by the Institute. Students failing to meet attendence requirements will be reported for possible penal actions.

Prerequisites: CSL201 (Data Structures) or equivalent Recommended : CSL105 (Discrete Structures)

Contents. Review of basic data structures and their realization in object oriented environment. The following topics will be covered with emphasis on formal analysis and design, Dynamic Data structures; 2-3 trees, Red-black trees, binary heaps, binomial and Fibonacci heaps, Skip lists, universal hashing. Data structures for maintaing ranges, intervals and disjoint sets with applications. Basic algorithmic techniques like dynamic programming and divide- and-conquer, Sorting algorithms with analysis, integer sorting, selection, Graph algorithms like DFS with applications, MSTs and shortest paths.
