I made the appropriate changes and ran it again for my own edification. ----- eplex_10.ecl % Run in this way: mip_example(X,Y,Cost). % From http://eclipseclp.org/doc/libman/libman060.html#toc67 entitled 10.2.6 Examples /* Results: ?- mip_example(X, Y, Cost). X = 2 <<<<<<====== X is printed as an integer, 2, not a decimal, 2.0. (Nicely done.) Y = 2.0 Cost = 2.0 Yes (0.00s cpu) No integer variables - nothing to do (in orange letters) */ :- lib(eplex). :- eplex_instance(my_instance). mip_example(X,Y,Cost) :- my_instance: (X+Y $>= 3), my_instance: (X-Y $= 0), my_instance: integers([X]), % This is a mixed integer problem. my_instance: eplex_solver_setup(min(X)), my_instance: eplex_solve(Cost), % retrieve typed solution my_instance: eplex_get(vars, Vars), my_instance: eplex_get(typed_solution, Vals), Vars = Vals. ----- I have read both of your replies and understand the points made in both.
