Hi,
When CPXmipopt call have finished, I want to get information about: running time (is possible real cpu time? using the interactive cplex I read it, so I think that this time is available) and optimum (objective) value of linear relaxation of the model (the original model, that is the first one that cplex optimize at node 0 and without using presolvers).

I don't know why, I set CPX_PARAM_TILIM using CPXsetintparam(env, CPX_PARAM_TILIM, 1800) but the solver runs and don't stop (in one call to CPXmipopt). Any idea? (I'm running CPLEX on SunOS)

Thanks in advance!
Hernan

The CPX_PARAM_TILIM is a double parameter. Thus, you need to set it with CPXsetdblparam() instead of CPXsetintparam().

The method should have returned a CPXERR_BAD_PARAM_NUM error as status code. Did you check the return status?

That was the problem! I have fixed it, Thanks!
