We study optimization problem with linear objective function subject to fuzzy linear system of equations as constraint, when the composition is in f → in BL-algebra. The algorithm for solving fuzzy linear system of equations is provided by algebraic-logical properties of the solutions. We present...
其中一种情况就是linear programming。在linear programming中(简称LP),我们给出一组线性的不等式,或者给出一组约束,用来定义一个polyhedron(可以为空,也可以是unbounded的),称之为feasible region。然后给定一个目标函数objective function(线性的),它受制于feasible region,我们要找到它的最大值或最小值。一般表达为...
形如\max_{i=1,...,m} (\textbf{c}_i' \textbf{x} + d_i) 的函数被称为 分段线性凸函数 (piecewise linear convex function). 一个简单的例子是 f(x) = |x| = \max\{ x, -x\} , 如图1.2(b)所示, 分段线性凸函数可以被用于近似一般凸函数....

For example, we may wish to minimize a linear function \[x_1 + 2 x_2 - x_3\] under the constraints that \[x_1 + x_2 + x_3 = 1, \quad x_1, x_2, x_3 \geq 0.\] The function we minimize is often called the objective function; in this case we have a linear ...
Write the objective function. f = @(x) -x2fx(x,'quadratic')*mdl.Coefficients.Estimate; I wonder how -x2fx(x,'quadratic') is obtained in this example? I did not see it from the linear model Cheers 댓글 수: 0 댓글을 달려면 로그인하십시오. ...

其中矩阵D是由m行Di(行向量)组成的矩阵,矩阵A是由r行Ai(行向量)组成的矩阵,那么这种特殊情况下的凸优化问题,叫做Linear Programming问题。下图给出了在二维的polytope的可行域内(大部分问题是n维的),图中的objective function(虚线所示,同一条虚线上f(x)的值是相等的)f(x)的最优解在最下面的点x⋆。
