如果代价函数最小值为负无穷,称这个问题为unbounded 等号约束可被视为两个不等约束 线性优化问题的标准形式 函数凸性 处理绝对值的两种方法 1.视为分段函数,绝对值应当大于等于x和-x 2.变量替换,记x=x^+-x^-,\left| x \right|=x^++x^- chapter 2: the geometry of linear programming 多面体polyhodra,...
LinearProgrammingModelsChapter31線性規劃模式 LinearProgrammingMode線性規劃模型(LinearProgrammingmodel)是在一組「線性」的限制式(asetoflinearconstraints)之下,尋找極大化(maximize)或極小化(minimize)一個特定的目標函數(objectivefunction)線性規劃模型由下列三個部分組成:一組決策變數(Asetofdecisionvariables)一個特定的...
,xn 被称作 决策变量 (decision variables), 且满足所有约束的向量 x 被称作一 可行解 (feasible solution) 或可行向量 (feasible vector). 所有可行解的集合被称作 可行集 (feasible set) 或可行域 (feasible region).若 j 既不在 N1 也不在 N2 中, 则 xj 符号没有限制, 那么我们称 xj 是自由变量 (...
2 by the fundamental theorem of linear programming , a linear programming problem is either infeasible, unbounded (which for a minimization problem means it has feasible solutions with arbitrarily large negative objective values) or has an optimal solution. if c ≥ 0 c ≥ 0 a...
