CS231: Introduction to the Design and Analysis of Algorithms

Fall 2003: T, Th 1:00 - 2:25 in Searles 126

This course is an introductory undergraduate course on the design and analysis of algorithms building on the concepts from CS210 (Data Structures). It introduces a number of basic algorithms for a variety of problems such as searching, sorting, selection and graph problems. It discusses analysis techniques, such as recurrences and amortization, as well as algorithm design paradigms such as divide-and-conquer, dynamic programming, and greedy algorithms.

Prerequisites: CS210 and either Math189 or CS200 (or permission of the instructor)

Grading policy

• Homework assignments (approx. 30%).
• Two in-class exams (20% each) and a final exam (30%).
• Class participation (tiebreaker).

Assignments

Homework assignments will be made available online as the semester progresses. Since solutions are handed out the day the homework is due, no credit is given for homework problem solutions received late. For special situations contact Laura (in advance).
Homework policy:

• Write your name on each sheet.
• Write the solutions in the space provided.
• Collaboration is allowed, even encouraged, provided that it helps you study better. Remember that exams are individual! The names of the collaborators should be listed along with the solutions and solutions must be written up individually.
• Homework should be submitted at the beginning of class on the due date.
• You are encouraged to type the solutions!
