    3. Test if the start solution is feasible

    Also, I wanted to clarify, I wasn't quite correct when saying there is unique completion for the partial solution. There are more feasible solutions. Like in the above example, xs can take smaller ...

    3. Test if the start solution is feasible

    Also, I wanted to confirm one thing. For the below code, Gurobi saying "User MIP start did not produce a new incumbent solution" just means that it already knows the start solution right? i.e. sinc...

    import gurobipy as gpimport randomNUM = 10000UB = 8m = gp.Model('test')xs = m.addVars(range(NUM), vtype=gp.GRB.INTEGER, lb=1, ub=UB, name='x')ys = m.addVars(range(NUM), vtype=gp.GRB.CONTINUOUS, lb=...

    3. Test if the start solution is feasible

    That was the first thing I checked, the bound, constraint, and integrality violation, all are < 1e-14. The problem we are trying to diagnose is Gurobi taking a lot of time to find a feasible soluti...

    3. Test if the start solution is feasible

    I am facing the same issue, I provide a partial start solution (there is a unique completion to this partial solution) and Gurobi says: "User MIP start did not produce a new incumbent solution.". F...
