Add ability to reset basis matrix

Open odow opened this issue 2 years ago • 2 comments

From a discussion with @joaquimg:

Add HiGHS options for resetting the basis and refactoring the matrix, so that the model is in a "just been built" state without actually needing a rebuild.

This probably requires changes to upstream HiGHS.

Xpress has XPRS_KEEPBASIS or XPRS_REFACTOR (to fix with links)
