On Network Simplex Method Using the Primal-dual Symmetric Pivoting Rule
نویسندگان
چکیده
We consider a network simplex method using the primal-dual symmetric pivoting rule proposed by Chen, Pardalos, and Saunders. For minimum-cost network-flow problems, we prove global convergence of the algorithm and propose a new scheme in which the algorithm can start from an arbitrary pair of primal and dual feasible spanning trees. For shortest-path problems, we prove the strongly polynomial time complexity of the algorithm.

Some new results on semi fully fuzzy linear programming problems
There are two interesting methods, in the literature, for solving fuzzy linear programming problems in which the elements of coefficient matrix of the constraints are represented by real numbers and rest of the parameters are represented by symmetric trapezoidal fuzzy numbers. The first method, named as fuzzy primal simplex method, assumes an initial primal basic feasible solution is at hand. T...
متن کاملOn the number of solutions generated by the dual simplex method
In this short paper, we give an upper bound for the number of different basic feasible solutions generated by the dual simplex method with the most negative pivoting rule for LP. The bound is comparable with the bound given by Kitahara and Mizuno (2010) for the primal simplex method. We apply the result to the maximum flow problem and get a strong polynomial bound.
متن کاملAn Upper Bound for the Number of Different solutions Generated by the Primal Simplex Method with any Selection Rule of entering Variables
Kitahara and Mizuno (2011a) obtained an upper bound for the number of different solutions generated by the primal simplex method with Dantzig’s (the most negative) pivoting rule. In this paper, we obtain an upper bound with any pivoting rule which chooses an entering variable whose reduced cost is negative at each iteration. The bound is applied to special linear programming problems. We also g...
متن کاملParametric linear programming and anti-cycling pivoting rules
The traditional perturbution (or lexicographic) methods for resolving degeneracy in linear programming impose decision rules that eliminate ties in the simplex ratio rule and, therefore, restrict the choice of exiting basic variables. Bland's combinatorial pivoting rule also restricts the choice of exiting variables. Using ideas from parametric linear programming, we develop anti-cycling pivoti...
متن کاملHigh performance simplex solver
The dual simplex method is frequently the most efficient technique for solving linear programming (LP) problems. This thesis describes an efficient implementation of the sequential dual simplex method and the design and development of two parallel dual simplex solvers. In serial, many advanced techniques for the (dual) simplex method are implemented, including sparse LU factorization, hyper-spa...
