Hello, I am using GLPK through the C API. I am using it on the Mac, installed by MacPorts, version: GLPK Simplex Optimizer, v4.65. I am using it to solve an integer linear programming problem. The function I call is glp_intopt.
It works, but I cannot figure out how to suppress output from this routine. I have tried this: glp_iocp parm; glp_init_iocp(&parm); ... parm.presolve = GLP_ON; parm.msg_lev = GLP_MSG_OFF; ... glp_intopt(prob, &parm) Setting the level to GLP_MSG_OFF helps —— it gets rid of some of the output —— but does not get rid of all the output. For example, I still get this: ... Long-step dual simplex will be used Applying PROXY heuristic... Proxy's time limit set to 10 seconds. Proxy's relative improvement set to 1.00 %. Searching for a feasible solution... >>>>> first solution = 3.000000e+00; Time used: 0.7 secs. Memory used: 0.2 Mb Starting proximity search... Bound exceeded = -6.000000. Proxy heuristic terminated. Time used: 0.7. Memory used: 0.2 Mb Objective value: 3.000000 ... Any idea how to suppress this, or at least direct it to a file, using the API? Thanks, Steve
