I have a list, which, for N = 5 (for instance), it is like this: [3*(1-_#0(0..1)),2*(1-_#18(0..1)),1*(1-_#36(0..1)),4*(1-_#54(0..1)),2*(1-_#72(0..1))]. I am working on a finite domain constraint environment and I tried this max_list(MaxFilter, M0), and I got this error (since the variable does not have a value at this moment) uncaught exception: error(type_error(evaluable,_#4195373(0..1)),(=<)/2) In Eclipse, I would use eval and in SWI, I used this predicate lmax([H|T], X):- foldl(max_, T, H, Exp), X #= Exp. max_(E, X, max(E, X)). but I did not find any equiivalent of foldl in GNU. What should I do? Any ideas? I am stuck and I have been searching the whole internet for days... //G. Samaras
