Forwarding to the python-projects mailing list where such question should be asked! People should probably think to Cc Mohamed if they have an answer.

--- Begin Message ---hello, I need your help, I use the "logilab-constraint" package for solving a combinatorial problem with constraints that are similar to the constraints of problem magic square, variables = [] domains={} constraints=[] for var in range(n*n): variables.append(var) domains[var]=fd.FiniteDomain([0,1,2,3]) #begin constraints I try to express the following constraint: the sum of each matrix row must be equal to 10 I expressed this constraint with python-constraint package as follows and it works for row in range(n): problem.addConstraint(ExactSumConstraint(10), [row*n+i for i in range(n)]) but i like to express this constraint with the "python-logilab-constraint" #end constraints r = Repository(variables,domains,constraints) solution=Solver().solve_one(r) print solution big thinks for you
