Dear All, I am solving a minimization MIP in which I have added a parameter lower bound. The intention is to stop the execution in a particular node in the branch and bound tree if the feasible solution at any point is less that the lower bound. cplex.setParam(IloCplex::CutLo,sol_cut); sol_cut is a constant for a particular problem. But this parameter doesnt seem to function at all. `For example, sol_cut for a particular instance was 8.4e+10 while cplex found a feasible solution of 2.4e+10 and it continues branching with no regard for the parameter. Any help in this regard will be greatly appreciated. Thank you.

Have a look at the CPLEX parameters manual. CutLo applies only to You can use an incumbent callback to stop the solver once a specified objective value has been attained.
