  4. Course Material • Textbook: Discrete Mathematics with Applications Author: Susanna S. Epp Publisher: Brooks/Cole • Notes: Course notes from “mathematics for computer science” http://courses.csail.mit.edu/6.042/spring07/ (available to be downloaded in the course homepage)

  5. Course Requirements • Quizzes, 45% • Final Exam, 55% Three Quizzes: (1) Sep 26 (Monday), in class (2) Oct 24 (Monday), in class (3) Nov 28 (Monday), in class

  6. A B C Topic 1: Counting • Sets and Functions • Combinations, Permutations, Binomial theorem • Counting by mapping, pigeonhole principle • Recursions Probability, data structures, algorithms

  7. Topic 1: Counting How many steps are needed to sort n numbers? Algorithm 1 (Bubble Sort): Every iteration moves the i-th smallest number to the i-th position Algorithm 2 (Merge Sort): Which algorithm runs faster?

  8. Topic 2: Logic and Proofs How do computers (and humans) think? Logic: propositional logic, first order logic Proof:induction, contradiction Artificial intelligence, database, circuit, algorithms

  9. Topic 3: Graph Theory • Graphs • Degree sequence, Eulerian graphs, isomorphism • Trees • Matching • Coloring Computer networks, circuit design, data structures

  10. Topic 3: Graph Theory How to color a map? How to schedule exams? How to send data efficiently?

  11. Tentative Course Schedule

  12. Objectives of This Course • To learn basic mathematical concepts, e.g. sets, functions, graphs • To be familiar with formal mathematical reasoning, e.g. logic, proofs • To improve problem solving skills, e.g. induction, recursion • To see the connections between discrete mathematics and computer science Knowledge will be used in future courses: CSC 2100, ERG 2040, CSC 3130, CSC 3160
