Re: logical equations & binary variables

Just include the following constraint:

m-Mx <=0

where M is an upper bound for m.

Optimal Basis

I have a problem with a LP I am solving with GAMS. I have a total of 576 variables, 409 constraints (all equality constraints). The problem is that I need to identify the optimal basis, however only 402 variables have zero marginal values so I cannot find the inverse of the basis as it is not square...
