This course provides an introduction to the design and analysis of computer algorithms, with a particular emphasis on the use of principles of mathematical induction in designing algorithms. Its goal is to acquaint the students with basic computer algorithms and their design principles and to cultivate the students' ability in designing and analyzing algorithms independently.
