This is a method for niimerically determining local minima of differentiable functions of several variables. In the process of locating each minimum, a matrix is determined which characterizes the behavior of the function about the minimum. For a region in which the function depends quadratically on the variables, no more than N iterations are required, where N is the nunnber of variables. By suitable choice of starting values and without modification of the procedure, linear constraints can be imposed upon the variables.
