  • 1.  Using CPLEX without branching

    Posted Mon April 26, 2021 09:51 AM
    I would like to use only the cutting-plane algorithm without branching in CPLEX. For this purpose, I set the MIP node limit into 0; I expected CPLEX to add cuts until the solution was found. But instead, it finished with no solution (there is a solution I checked it a branch-and-cut method). Why does it happen? How can I use only cuts until the solution is found? Any help would be appreciated!
