Thomas Neidhart commented on MATH-842:
--------------------------------------
I dont see the need to make it generic, withOptions(SimplexSolverOptions)
should be specific to the SimplexSolver. Other solvers might have other options
specific to them, that alter the behavior of the solver.
Without specifying such options the solver would be initialized with default
options.
I understand that there are "generic" options almost each solver supports, like
maxIterations, but thats almost everything the solver have in common, afaict.

>
> As a consequence of MATH-828, Bland's rule has been introduced to prevent
> cycling. Now there are cases where cycles can still occur (see
> testMath828Cycle in SimplexSolverTest). These cases have for now been solved
> with a simple heuristic:
> * after maxIterations / 2 -> ignore Bland's rule
> This issue has been created to further investigate the problem and come up
> with a cleaner solution.
