What This Document Is
These are detailed session notes from an Introduction to Discrete Structures (COT 3100C) course at the University of Central Florida. This resource focuses on the foundational principles of counting and combinatorial analysis – essential building blocks for more advanced computer science and mathematical topics. It’s designed to supplement lectures and provide a structured overview of key concepts.
Why This Document Matters
This material is incredibly valuable for students enrolled in COT 3100C, or anyone seeking a solid grounding in discrete mathematics. It’s particularly helpful when tackling problems involving arrangements, selections, and the distribution of items into categories. These notes can be used for review before quizzes and exams, as a reference while working through homework assignments, or as a refresher on core concepts later in your studies. Understanding these principles is crucial for fields like algorithm design, probability, and cryptography.
Topics Covered
* Fundamental counting principles (product rule, sum rule)
* Counting functions between sets
* One-to-one and onto functions
* Subsets of a given set
* The Inclusion-Exclusion Principle
* The Pigeonhole Principle (both standard and generalized forms)
* Permutations and Combinations – definitions and relationships
* Binomial Coefficients and their properties
* Pascal’s Identity and the construction of Pascal’s Triangle
What This Document Provides
* A comprehensive overview of core counting techniques.
* Explanations of important theorems related to combinatorics.
