Add ability to reset basis matrix #192

Closed odow closed 1 month ago

odow commented 5 months ago

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)

Upstream issue is https://github.com/ERGO-Code/HiGHS/issues/1598

This can wait until it is available upstream.
