The introduction of course –Combinatorics

Combinatorics is a foundational and limited-optional specialty course for undergraduates majoring in computer science and technology,; this course is a very interesting and useful course which involves discrete structures and builds up a good combinatorial thinking for computer science students.

  Through this course, students will:

1. Use inclusion-exclusion principle, generating functions, Polya counting etc. to solve the problems such as permutation combination, set partition, integer partitions.

2. Master the counting technique of recurrence relations and how to solve the linear nonhomogeneous Recursive Relation with constant coefficients.     

3. Learn the basics of existence proof and combinatorial identity proof.

4. Learn the constructive algorithms and optimization algorithms.

  This course emphasizes on combinatorial counting techniques. The contents contain the Pigeonhole principle, the binomial coefficients, the inclusion-exclusion principle, recurrence relations, generating functions, Polya counting and their applications, special counting sequences, generating permutations and combinations and combinatorial optimization algorithms.

  Study of this course makes students to grasp the basic theorems, principles and algorithms of Combinatorics, and improve the ability to combinatorial thinking and skill in solving the practical problems.
