Top Previous Next |

To run the solution process use the menu LiPS >> Solve Model. Model Solver has two modes: basic and advanced. In the basic mode (which is suitable for learning the simplex method) LiPS provides not only an answer, but a detailed solution process as a sequence of simplex tables. At each iteration, the output includes: corresponding simplex table, variable to be made basic, variable out of the basic set, etc. The form of the computer solution simulates the process of manual solution of the problem (an artificial basis, an intelligent choice of initial basis, fractions, etc.). In advanced mode LiPS provides a set of methods for solution of the large-scale problems: a modified primal and dual simplex method based on LU-decomposition, branch-and-bound method for MILP. |
