The computation of the basis inverse is the most time-consuming step in simplex type algorithms. This inverse does not have to be computed from scratch at any iteration, but updating schemes can beâ€¦ (More)

The simplex method is perhaps the most widely used method for solving linear programming (LP) problems. The computation time of simplex type algorithms depends on the basis inverse that occurs inâ€¦ (More)

Pricing is a significant step in the simplex algorithm where an improving nonbasic variable is selected in order to enter the basis. This step is crucial and can dictate the total execution time. Inâ€¦ (More)

This paper describes the use of the Specification and Description Language (SDL) for the implementation of Abstract Test Suites (ATS). The Tree and Tabular Combined Notation (TTCN) is the standardâ€¦ (More)

Linear programming algorithms have been widely used in Decision Support Systems. These systems have incorporated linear programming algorithms for the solution of the given problems. Yet, the specialâ€¦ (More)

Simplex type algorithms perform successive pivoting operations (or iterations) in order to reach the optimal solution. The choice of the pivot element at each iteration is one of the most criticalâ€¦ (More)
