| 内容記述 | In many mathematical problems, it is necessary to determine the minimum and maximum of a function of several variables, limited by various linear and nonlinear inequality constraints. It is seldom possible, in practical applications, to solve these problems directly. In most cases, an iterative method must be used to numerically obtain a solution. The CONMIN program was developed to numerically perform the minimization of a multi-variable function subject to a set of inequality constraints. The function need not be a simple analytical equation; it may be any function which can be numerically evaluated. The basic analytic technique used by CONMIN is to minimize the function until one or more of the constraints become active. The minimization process then continues by following the constraint boundaries in a direction such that the value of the function continues to decrease. When a point is reached where no further decrease in the function can be obtained, the process is terminated. Function maximization may be achieved by minimizing the negative of the function. This program is written in FORTRAN IV for batch execution and has been implemented on a CDC 6000 series computer with a central memory requirement of approximately 43K (octal) of 60 bit words. The CONMIN program was originally developed in 1973 and last updated in 1978. |
