I am working on a research project developing an algorithm that can solve the node relaxation of a certain class of integer programs faster than dual simplex. I am wondering if there is a way I replace gurobi's dual simplex code for node relaxation with my own code but still use gurobi's branch-and-bound code.

  Hi Ruofeng,

  You would have to use an open source solver for this, eg HiGHS or SCIP.
