Abstract:

Based on modifying the search direction of classic wideneighborhood algorithm, a new wideneighborhood interior point algorithm for linear programming was proposed. The convergence analysis of the new algorithm was presented. And the algorithm enjoys the iteration bound  O(nL), the same as the complexity result for classic wideneighborhood interior point method. The numerical calculation shows that the new algorithm is efficient.

Key words: linear programming, interiorpoint methods, wideneighborhood algorithm, polynomial complexity
