In the fast-evolving world of computer science, mathematical thinking is the invisible engine driving algorithms, logic, and computational efficiency. Discrete Mathematics for Computer Science equips learners with the mathematical tools and logical reasoning necessary to excel in areas such as programming, software development, data science, cybersecurity, and theoretical computing.
This textbook (available in several editions) emphasizes precision, problem-solving, and the bridge between abstract concepts and practical applications. Written with students of computer science in mind, it covers a wide range of topics foundational to computing and algorithmic design.
This section introduces formal logic, which is the foundation of programming and reasoning in computer science:
Logical operators, truth tables, tautologies.
Predicate logic and quantifiers (universal ∀, existential ∃).
Logical equivalences, implications, and proofs.
Applications in software verification, logic circuits, and AI.
Understanding how to construct proofs is essential in algorithms and complexity theory.
Direct proof
Proof by contradiction
Mathematical induction and strong induction
Applications in recurrence relations and loop invariants
Sets are the language of data structures:
Basic operations: union, intersection, complement
Power sets and Cartesian products
Venn diagrams and applications in relational databases
The concepts of functions and mappings are fundamental in programming:
Injective, surjective, bijective functions
Inverse functions and function composition
Binary relations, equivalence relations, and partial orders
Applications in modeling state machines and program behavior
Critical in computer security, hashing, and coding theory:
Divisibility and prime numbers
GCD, LCM, Euclidean Algorithm
Congruences and modular systems
Cryptography applications (e.g., RSA encryption)
Counting principles allow for performance estimation and problem modeling:
Permutations, combinations
Pigeonhole Principle
Binomial Theorem and Pascal’s Triangle
Inclusion-Exclusion Principle
Discrete probability and expected values
Vital in analyzing recursive algorithms:
Defining and solving linear recurrence relations
Applications in Fibonacci numbers, binary search trees, and divide-and-conquer algorithms
Using induction to prove properties of recursive programs
A critical component in networks, AI, and data organization:
Graph types (directed, undirected, weighted)
Paths, circuits, connectivity
Breadth-First and Depth-First Search (BFS, DFS)
Minimum spanning trees, Dijkstra’s algorithm
Applications in social networks, maps, and routing
Used extensively in hierarchical data storage and search:
Binary Trees, Binary Search Trees (BST), AVL Trees
Tree traversals: Preorder, Inorder, Postorder
Applications in parsing, file systems, and decision-making processes
The mathematical backbone of digital electronics and computer logic:
Boolean expressions and truth tables
Simplification using identities and Karnaugh maps
AND, OR, NOT, NAND, NOR gates
Applications in computer architecture and digital design
Introduction to algorithmic thinking
Time and space complexity
Big-O notation
Basic sorting and searching algorithms
Clarity and Structure: Each topic is introduced with motivation, definitions, examples, and guided exercises.
Computer Science Integration: Every mathematical idea is linked directly to computing—through algorithms, logic, or programming paradigms.
