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 (it's obviously 409 x 402). What should I do?
