How to test the performance of a Prolog program?

Question

Is there any way to do some benchmarking on several Prolog programs? I am using SWI-Prolog, and it doesn\'t show the time taken to execute the query!!

Answer 1

What about time/1? In SWI-Prolog, try:

?- time(your_goal).

and

?- profile(your_goal).
