MIP solution process - updating the incumbent objective value

    In the MIP process log, the incumbent column shows the objective value of the current best feasible solution. The node objective column shows the objective of the relaxation of the node. This does not mean that there is a feasible solution for the MIP model with this objective. Most of the time, the solution of the node relaxation will violate some of the integrality constraints. (In fact, you can see the number of integrality constraints violated by this solution in the IntInf column.)

    You can find more information about the MIP log here.
