Extremization of Constrained Multivariable Function: Structural Programming

This paper describes how to find the extremum of a constrained multivariable function by taking advantage of its structure. Three steps lead to the solution. The first step discusses restructuring a given problem¿reformulating it in a way which makes possible the calculations performed in the next two steps. The second step presents the conversion of the restructured problem into a block diagram. The last step presents the problem solution from the block diagram obtained.
