Initializing help system before first use

The MIP search tab of the Run Bar

barrunmip.png

The graph on top shows the evolution in time of the MIP gap during the global search. Also shown are the points where the integer solutions were found and the depth in the search tree at which each solution was found.

The graph below shows the progress of the current best integer solution objective relative to the best bound. Integer solutions are marked as well.

  • The graphs can be zoomed in and out and each curve can be shown or hidden using the checkboxes in the graph legend.
  • Use the slider bar to change the vertical size of either graph.
  • Pressing the button "Accept current best solution and continue" will terminate the MIP search but the execution of the Mosel model will continue. This behavior is unlike that of the Stop button, which stops the entire model.
  • Xpress-IVE maintains a history of the last ten graphs produced. Select the desired graph from the list at the top. Note that the graph history cannot be accessed during an optimization.
