COMPSCI 311: Introduction to Algorithms

Hung Le and Marius Minea

Spring 2021

Welcome to the Spring 2021 homepage for COMPSCI 311: Introduction to Algorithms.
The course will be co-taught by Prof. Hung Le and Marius Minea. The two sections will share TAs and graders, Moodle, Campuswire and Gradescope sites, and there will be common assignments, quizzes, and midterms, and same or similar finals.

Description This course will introduce you to algorithms in a variety of areas of interest, such as sorting, searching, string-processing, and graph algorithms. You will learn to study the performance of various algorithms within a formal, mathematical framework. You will also learn how to design very efficient algorithms for many kinds of problems. Mathematical experience (as provided by COMPSCI 250) is required. You should also be able to program in Java, C, or some other closely related language. Prerequisites: COMPSCI 187 and either COMPSCI 250 or MATH 455.
