Traditionally Canterbury Cricket Week has included a Ladies day with prizes being awarded for the best hat on the day.
Tree automaton For a top-down automaton, a ground term "t" is accepted if there exists a reduction that starts from "q"("t") and ends with "t", where "q" is an initial state. The tree language "L"("A") accepted, or recognized, by a tree automaton "A" is the set of all ground terms accepted by "A". A set of ground terms is recognizable if there exists a tree automaton that accepts it. A linear (that is, arity-preserving) tree homomorphism preserves recognizability. A non-deterministic finite tree automaton is complete if there is at least one transition rule available for every possible symbol-states combination. A state "q"
