Abstract:

The arcsearch interiorpoint algorithm was used to solve the linear programming problem and the iteration complexity O(n3/4L) was obtained for this algorithm. The proposed algorithm was used to search for the optimizers along the ellipses in a wide neighborhood of the central path. The numerical results show that this algorithm is efficient.

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