The paper is devoted to comparison of two methodologically different types of mathematical techniques for coping with network’s flows assignment problem. Gradient descent and projection approach are implemented to the simple network of parallel routes (there are no common arcs for any pair of routes). Gradient descent demonstrates zig-zagging behavior in some cases, while projection algorithm converge quadratically in the same conditions. Methodological interpretation of such phenomena is given.
