Description
It is often useful when solving linear programs to see which constraints are tight.... And so there should be a way to do it in Sage !!!

Perhaps there should be a
MixedIntegerLinearProgram
method similar toget_values
that retrieves the values of the constraint functions at the current solution; its input should be the same as the input toconstraints
.Note also that some backends already have support for getting this kind of information, for example GLPK has
get_row_prim
.
