- Oct 23, 2026 Testing DFA Equivalence with Union-Find Instead of a Product Table Why two machines accept the same language exactly when no reachable pair is split by acceptance, and how merging pairs in a disjoint-set structure avoids building the product. computation theory
- Mar 10, 2023 Product Constructions: Intersection, Union, and Complement Without Rebuilding How pairing states from two machines computes a boolean operation on their languages, why complement needs a total transition function, and what the product costs in states. computation theory
