WebbThat is accomplished by a method due to C. E. Lemke [ ] which is ucually called the dual simplex method. We shall rst describe it as a mirror image of the simplex method and … 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…
