WebCome trovare gli stati indistinguibili di un automa. Per trovare gli stati in un automa AFD posso usare l' algoritmo di Hopcroft. Creo una tabella con tutte le combinazioni tra gli stati dell'automa. Poi la trasformo in triangolare per evitare i confronti duplicati. Elimino le combinazioni in cui uno stato è finale e l'altro non è finale.

WebHopcroft-Karp Algorithm has time complexity of O(√(V)E) — analysis omitted for now. This allows us to solve MCBM problem with V ∈ [1000..1500] in a typical 1s allowed runtime in many programming competitions — the similar range as with running Dinic's algorithm on Bipartite Matching flow graph. In computer science, the Hopcroft–Karp algorithm (sometimes more accurately called the Hopcroft–Karp–Karzanov algorithm) is an algorithm that takes a bipartite graph as input and produces a maximum-cardinality matching as output — a set of as many edges as possible with the property that no two edges … Meer weergeven A vertex that is not the endpoint of an edge in some partial matching $${\displaystyle M}$$ is called a free vertex.
