Saving a sequence of tableaux is accomplished by saving the page
in your browser. However, while it may be useful later to load that page
into your browser so that you may continue working on the problem, you
will not be able to pivot on it. Instead, you must open a new tab,
copy it over and work in the new tab.
Exploration and discovery is facilitated by employing multiple
tabs. From a tab labeled X, use the
to Copy Tableau to New Window. Doing that several times opens
new windows (better yet, tabs --- see
) with labels XA, XB, etc. From these identical tableaux one can
perform different pivots for comparison, among other inquiry-based
When solving ILOPs via cutting planes, when it comes time to
add a new constraint, you must add a new slack variable column as well.
Instead of adding them separately, you can add them at the same time
by using Add Row and Column After in the menu of the cell after
which you want them added.
When solving ILOPs via branch and bound, follow the same advice
as for cutting planes, above, regarding the inclusion of new constraints.
Also, use new tabs (as in the exploration advice, above) for the
