Webb23 juni 2024 · From the book “Linear Programming” (Chvatal 1983) The first line says “maximize” and that is where our objective function is located. That could also say “minimize”, and that would indicate our problem was a minimization problem. The second and third lines are our constraints.This is basically what prevent us from, let’s say, … Webb-1 can generate the whole Simplex tableau, and hence can execute the Simplex method.
