CS 351 Syllabus

Data Structures and Algorithms

Revised: August 2018

Course Description

This course covers more advanced data structures, well-known algorithms, algorithm design techniques, algorithm analysis, and mathematics related to selected algorithms. The goal is to help students learn to write and analyze efficient programs that solve common and difficult problems. Data structures covered include representations of graphs, binary search trees, balanced binary search trees, AVL trees, heaps, and hash tables. Well-known algorithms covered include several sorting algorithms (such as insertion sort, merge sort, and Shell sort), binary search, and a sampling from other areas such as graph algorithms and NP-hard problems. Mathematics related to advanced algorithms and data structures will also be investigated. Mathematics covered may include, but are not limited to, probability and its application to Bayesian networks, Markov chains and decision processes, and Monte Carlo simulations; introduction to machine learning; and applications of linear algebra. Algorithm design techniques the students will practice include dynamic programming, divide-and-conquer, and greedy techniques.
