Simple question, how can I shuffle a list in PROLOG, so that A1 is my new list?
shuffle([1,1,1,2,3,4],A1),
I've tried a few predicates I found on the web but none of them seems to be working. Also found this but apparently it's not available anymore, according to SWI-PROLOG.
回答1:
You can use random_permutation/2. It is available in SWI-Prolog.
?- random_permutation([1,2,3],L).
L = [1, 3, 2].
