Hi there!
I am using PPL 1.0pre1 (GIT version) with SWI-Prolog 6.1.3 and I think I find a bug wrt PIP:
Call: (8) ppl_new_PIP_Problem_from_space_dimension(6, _G10879) ? skip Exit: (8) ppl_new_PIP_Problem_from_space_dimension(6, 935460) ? creep Call: (8) ppl_PIP_Problem_add_constraints(935460, [A-B-C+D>=0, F= -A+B+E, D= -1-A+B+C]) ? creep Exit: (8) ppl_PIP_Problem_add_constraints(935460, []) ? Call: (8) ppl_PIP_Problem_is_satisfiable(935460) ? skip Exit: (8) ppl_PIP_Problem_is_satisfiable(935460) ?IMO, this last call should fail because the [A-B-C+D>=0, F= -A+B+E, D= -1-A+B+C] is not satisfiable. Note that [A-B-C+D>=0, D= -1-A+B+C] is correctly reported as unsatisfiable.
Do you confirm it's a bug from PIP?
Hi Fred.
Just to tell you that I am going to inspect what happens.
Thanks for reporting, Enea.
Thanks in advance, Fred
