摘要
We present an infinite series of n-state Eulerian automata whose reset words have length at least (n(2) - 3)/2. This improves the current lower bound on the length of shortest reset words in Eulerian automata. We conjecture that (n(2) - 3)/2 also forms an upper bound for this class and we experimentally verify it for small automata by an exhaustive computation.
