We give an algorithm which computes the set of descendants of a regular set R, for Thue systems of certain type. The complexity of the algorithm is \(O(m^ 3)\) where m is the number of states of an automaton recognising R. This allows to improve the known complexity bounds for some extended word problems defined by cancellation rules.
