Hi Vassilios,I am encountering a situation where with default values the MIP starts on 4 threads on my machine. Then, the same candidate integer XBar solution is encountered within the Lazy cut cal...

Hi VassiliosI have a query. I have not read the paper the OP posted.Is the CPX_PARAM_SOLNPOOLINTESITY setting of 4, documentation here: https://www.ibm.com/docs/en/icos/22.1.0?topic=parameters-solu...

Hello Simranjit,Thank you. That is indeed my workflow.I had one additional query. Does that fact that when I stop my own computations after, as you state:“Repeat until no more violated cuts are fou...

The min ratio test may give a movement length of 0. So, the non basic variable with negative reduced cost will enter the basis at value 0. So, it is a degenerate pivot.

Thank you. I will test these out. Regarding: "Advanced Start CPLEX: CPXPARAM_Advance (controls basis use in MIP/LP).Gurobi: No direct equivalent; use "Start" attribute for MIP warm starts." Since I...

Hi David, I have a follow-up to this. When it is stated that Gurobi implements the network simplex algorithm, does this mean that there is a C API which directly allows the user to input the nodes...

Thank you Marika. I have two follow up questions (1) Is there an example for adding usercuts via GRBcbcut as there is for lazycuts [tsp_c.c]? I did search on https://docs.gurobi.com/projects/exampl...
