problem.getlpsolval

Purpose

Used to obtain a single LP solution value following optimization.

Synopsis

x, slack, dual, dj = problem.getlpsolval(column=None, row=None)

Arguments

column	Column of the variable for which to return the solution value.
row	Row of the constraint for which to return the solution value.
x	The returned value of the primal variable.
slack	The returned value of the slack variable.
dual	The returned value of the dual variable ( c_B^TB^-1).
dj	The returned reduced cost for the variable ( c^T-c_B^TB^-1A).

Further information

1. This function is currently not supported if the problem is in a presolved state.

2. If column or row are None, the corresponding output is set to -xpress.infinity.
