======Algorithms, Fall 2023======
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.
