Simplex method for solving optimization problems of linear programming

The simplex method is a computational procedure based on the principle of sequential improvement of solutions during the transition from one base point (basic solution) to another. This improves the value of the objective function. The basic solution is one of the valid solutions that are at the vertices of the realm of valid values. […]

Classical theories of international trade and their evolution

The centuries-old history of world trade is based on the tangible benefits it brings to the participating countries. During this period, explanations of cause and effect have developed into concrete theories. The general theory of international trade gives an idea of what underlies this benefit from foreign trade or what determines the directions of foreign […]
