Note
|
On large problems, it may be beneficial to warm start progress by running a number of iterations with the barrier solver as specified by
XSLP_BARLIMIT. On some numerically difficult problems, the barrier may stop prematurely due to numerical issues. Such solves can sometimes be finished if crossover is applied. After
XSLP_BARSTALLINGLIMIT such attempts, SLP will automatically switch to use the dual simplex.
