Overview of Discrete Mathematics

Discrete Mathematics focuses on mathematical structures with distinct, non-continuous values, such as integers, graphs, and logic-based statements. The subject is divided into the following core areas:

• Mathematical Logic: Covers propositional and predicate logic, rules of inference, and formal proof methods.
• Sets and Relations: Explores set theory, operations, functions, sequences, summations, and matrix/graph representations.
• Mathematical Induction & Counting: Includes permutations, combinations, the Pigeonhole Principle, generating functions, and discrete probability.
• Boolean Algebra: Focuses on Boolean functions, algebraic theorems, and expression minimization.
• Optimization: Covers linear programming, the simplex algorithm, and PERT.
• Ordered Sets & Lattices: Studies partially ordered sets and Hasse diagrams.
• Probability Theory: Examines axioms, conditional probability, and distributions (Poisson, normal, exponential).
• Graph Theory: A major section covering graph types, traversals (DFS/BFS), shortest path algorithms (Dijkstra), spanning trees (Prim, Kruskal), and tree traversals.
• Special Graphs & Matching: Includes Eulerian and Hamiltonian graphs, the Traveling Salesman Problem, and matching algorithms.
• Vertex Colorings: Explores chromatic numbers, greedy coloring, planar graphs, and directed graph properties (Tarjan’s algorithm, connectivity).
• Group Theory: Introduces groups, subgroups, isomorphisms, rings, and fields.
