We are observing that in the barrier Linear Problem model Gurobi is mentioning the solution optimal before reaching the BarConVtol limit. If we set the limit to 1e-4 then it says result optimal as soon the gap reached 1e-2. If I set it to 1e-8 then gurobi says that optimal solution is 1e-6. Is there any other parameter which can over write this or any behaviour which can cause this issue?
Also is optimality tolerance is applicable to all algorithms or specific to some algorithm.
