The Stats tab of the Run Bar

During the optimization (solving) stage of a Mosel run, or when optimizing a matrix file, this window pane displays the state of the Xpress Optimizer.

Text is highlighted (black) when the status or activity is current or currently taking place. Text is dimmed (gray) when the status information depicted is no longer current (e.g., when the optimizer is processing a presolved matrix, the before-presolve matrix is not currently relevant) or if the activity described is either finished and still relevant (the LP relaxation statistics are useful during the global search phase) or not started yet.

The Time overheads section shows the approximate time spent by Xpress-IVE on tasks other than optimization. Note that the time overhead created by other programs (processes) running on the same machine is not accounted for, even though they can slow down the optimization significantly.
