Ross origionally wrote identical versions in C and Prolog with the C version being much faster. However, after studying the program using the Gauge performance analysis system, we were able to get the prolog performance within 25% of the C version. Both Gauge and the theorm prover were run under Sicstus prolog. The execution time for the prover was obtained using a preliminary version of a native code compiler. Carl
