Combinatory Logic and Graph Reduction Fundamentals

Understanding how functional expressions are computed under the hood is essential for grasping modern language runtimes and evaluation strategies. This text-based course guides you through the foundational principles of combinatory logic and graph-based execution models. You will gain a clear conceptual understanding of variable-free computation, learning how lambda abstractions translate into combinator terms and how graph structures efficiently evaluate recursive code. What you'll learn: - Understand core concepts of combinators including S, K, and I foundational combinators - Apply bracket abstraction algorithms to eliminate bound variables from lambda expressions - Implement Curry optimization techniques to simplify applicative subexpressions - Trace graph combinator reduction step by step to see lazy evaluation in action - Handle recursive expressions and cyclic graph structures without unbounded expansion - Connect graph reduction theory to modern functional programming compiler design The course begins by clarifying essential theoretical terminology and basic lambda calculus notations before walking you through abstraction techniques, reduction steps, and recursive graph dynamics. This course is designed for programmers, computer science students, and curious learners looking to understand functional evaluation models from the ground up, with no advanced mathematical background required.
