The Gurobi Optimizer produces a log that allows you to track the progress of the optimization. By default, the log is put to both the screen and to a file. Screen output can be controlled using the OutputFlag parameter, and file output can be controlled using the LogFile parameter.
The format of the log depends on the algorithm that is used to solve the model (simplex, barrier, sifting, or branch-and-cut). We now describe the contents of the log for each algorithm.
