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
like spanning trees and shortest paths. It discusses analysis
techniques, such as recurrences and amortization, as well as algorithm
design paradigms such as divideandconquer, dynamic programming, and
greedy algorithms.
Prerequisites: CS210 and either Math189 or CS200

Office hours: M,W after class 46pm. I will
normally be in the office the evening before homework is due, but do
not take it for granted and do not rely on it! Also, you can drop by
for a quick question any time I am in the office (and in a good
mood). Or, just send me an email to setup a (different) time.

Grading policy
 Homework assignments (approx. 30%).
 Two inclass 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!
