The potentially exponential cost of state space traversal is avoided and the redundancies found can all be removed at once. The optimised circuit is a safe delayed replacement of the original circuit. The algorithm computes a set of compatible sequential redundancies and simplifies the circuit by propagating them through the circuit.
