Dear Anshu, 1) You are missing N2 in param: ( for(I,1,N), param(X,N) do X[I]#> 0, X[I+1]#> X[I], X[N]#< N2 ), 2) I think you should add N to second param. The same with next set of loops. ( for(I,1,N),param(X,N) do (for(J,I,N),param(X,I) do (for(K,J+1,N),param(X,J) do I hope that helps Best regards -- [ Wit Jakuczun http://www.linkedin.com/in/jakuczunwit ] 2012/9/5 Anshu Shankar Prasad <anshu.sprasad.che10_at_itbhu.ac.in> > :-lib(ic). > > :-lib(branch_and_bound). > > solve(N,X):- > > N2 is N*N, > > dim(X,[N]), > > X[1..N] :: 1..N2, > > Z :: 1..N2, > > ( for(I,1,N),param(X,N) do > > (for(J,I,N),param(X,I) do > > (for(K,J+1,N),param(X,J) do > > X[K]-X[I]-X[J]#\=0 > > ) > > ) > > ), > > ( for(I,1,N),param(X,N) do > > ( for(J,I+1,N),param(X,I) do > > ( for(K,J,N),param(X,J) do > > ( for(L,K+1,N),param(X,K) do > > X[L]+X[I]-X[J]-X[K]#\=0 > > ) > > ) > > ) > > ), > > ( for(I,1,N),param(X,N) do > > ( for(J,I,N),param(X,I) do > > ( for(K,J,N),param(X,J) do > > ( for(L,K+1,N),param(X,K) do > > X[L]+X[I]-X[J]-X[K]#\=0 > > ) > > ) > > ) > > ), > > ( for(I,1,N), param(X,N) do > > > > X[I]#> 0, > > X[I+1]#> X[I], > > X[N]#< N2 > > ), > > > > > > Z#=X[N], > > > > X =..
