History-Deterministic Büchi Automata are Succinct
Abstract
We describe a history-deterministic Büchi automaton that has strictly less states than every language-equivalent deterministic Büchi automaton. This solves a problem that had been open since the introduction of history-determinism and actively investigated for over a decade. Our example automaton has 65 states, and proving its succinctness requires the combination of theoretical insights together with the aid of computers.
