comment How can I verify my linear program solutions?
It puzzles me though - I can't quite find the flaw in the procedure.

comment How to use the simplex method for linear programs?
@calculus: Well I'll be damned, I didn't know about that at all. So basically, the last row can only be modified by the pivot row? What about vice-versa - can the last row modify a row that is not the pivot, like $r_4 + r_1$?

@calculus: Hm, actually, I don't get it lol. What is the problem with that? This is probably what I'm missing.
