Method Summary

double	min() Get the minimum.
ImmutableVector	minimizer() Get a minimizing vector.

Method Detail

min

double min()

Get the minimum.

Returns:

the minimum

minimizer

ImmutableVector minimizer()

Get a minimizing vector.

In the case where the problem is unbounded, this minimizer is the same as the u vector on p.67 in "Michael C. Ferris, Olvi L. Mangasarian, Stephen J. Wright. "Linear Programming with MATLAB," Algorithm 3.1, Section 3, The Simplex Method."

Returns:

a minimizing vector, as a solution to the Linear Programming problem
