Abstract :
Most NP-completeness results for test generation problems involve a reduction to the redundancy problem, which explicitly encodes the satisfiability problem. In this correspondence we investigate the complexity of a more modest problem¿that of estimating the size of a test set under the constraint that the circuit is irredundant. We show that even this constrained problem is NP-hard in the strong sense.
