Renaud,
SYMPHONY has two built-in primal heuristics (shamelessly stolen from
Cbc), one of which is a rounding heuristic, but they are currently
turned off by default. To turn them on, set the parameter
"do_primal_heuristic" to 1. Just put the line
sym_set_int_param(env, "do_primal_heuristic", 1):
in your code before the call to sym_solve(). I can't promise it will
work miracles, but hopefully, it will help!
Cheers.
Ted
