Dear all,
Since the complexity is a little high in my ILP model, it takes long time to find the optimum value.So I want to get a sub-optimal value, how could I configure it in CPlex? Please help me.
thanks very much.

I suggest using a time limit, a node limit or a solution limit.
These limits are set using CPLEX parameters. See the parameter reference manual here, in particular the parameter lists.
The parameters I suggest to use are CPX_PARAM_TILIM, CPX_PARAM_NODELIM and/or CPX_PARAM_INTSOLLIM.

Hi thanks,but I want to set this limit in the optimizer instead of writing codes. Can I do that?

Look at the commands 'set timelimit' and 'set mip limits' in the interactive optimizer.
