...When the functions f , g 1 , ..., g m are linear expressions in the variables x 1 , ..., x n , it is called a linear program, and in other cases it is called a nonlinear program, but in particular when f is a quadratic expression and g 1 , ..., g m are linear, it is called a quadratic program. Also, when it is conditioned that some of the variables take integer values, it is called an integer program, and when the coefficients change stochastically, it is called a stochastic program. Mathematical programs are sometimes classified based on the structure of the problem, and network-based programming is one field within this. ... *Some of the terminology that refers to "stochastic programming" is listed below.

…関数f,g1,……,gmが変数x1,……,xnの一次式である場合を線形計画,それ以外の場合を非線形計画と呼ぶが,とくにfが二次式でg1,……,gmが一次である場合を二次計画という。また変数のあるものが整数値をとることが条件づけられている場合を整数計画といい,係数が確率的に変化する場合を確率計画という。 数理計画は問題のもっている構造をもとに分類されることもあるが,その中ではネットワーク型の計画法が一分野をなしている。… ※「確率計画」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
