ALGORITHM

The algorithm the optimizer currently is running / was running just before completition.

Integer

1	No LP optimization yet.
2	Dual simplex.
3	Primal simplex.
4	Newton barrier.
5	Network simplex.

If the barrier with crossover is used, the value of ALGORITHM during the crossover and the final clean up will reflect the algorithm used, but will be reset to barrier once the optimization is complete.
