I am testing several systems including Jess. I programmed it in Yap in a similar procedural way, since there is no easy way to implement it in prolog back-tracking systems, while this problem can be solved easily by constraint programming systems like DLV. I know the above procedural program is

I tried the brute force procedure search with a maximal depth limit, it is really slow. while in other systems (like yap)it much faster. In yap, I defined move(x,y) :- up(x,y). move(x,y) :- down(x,y). move(x,y) :- right(x,y). move(x,y) :- left(x,y). and keep all the seen state in a list to avoid
