WebbSomehow, we may use matrices, use matrix multiplication and whatever, to construct a tableau. Then you will even see that we don't really need to construct a whole tableau. Let's see how to do this, from the very beginning. What we want to introduce is the matrix representation, or you may say this is a way to implement the simplex method. The tableau form used above to describe the algorithm lends itself to an immediate implementation in which the tableau is maintained as a rectangular (m + 1)-by-(m + n + 1) array. It is straightforward to avoid storing the m explicit columns of the identity matrix that will occur within the tableau by virtue of B being a subset of the columns of [A, I]. This implementation is referred to as the "standard simplex algorithm". The storage and computation overhead is such t…
