HI, I m solving a MIP with cplex 10.1.1
I would like cplex stops the solving after the presolving precedure. That is, without branching from the root node. The only method pop out could be stop the procedure with a call back function at node 0.  I was wondering is there any other method, e.g. a parameter that can do the job?
Thanks!

If you set NodeLim to 0, CPLEX will presolve, apply cuts and heuristics at the root node, but stop without branching.
