Discrete mathematics is the branch of mathematics that studies the underlying principles which govern discrete structures and the binary universe. It has become popular in recent decades because of its applications to computer science and its bridging role between mathematics and communications and computing. Theory and techniques in discrete mathematics are well-coupled with applications and implementations. They also have the remarkable feature of being versatile and applicable to many disparate problems in computational biology, information retrieval, network design.
