MATLAB优化问题中核心是要掌握fmincon函数。官方解释为:“Find minimum of constrained nonlinear multivariable function”。关键词为:约束,非线性。 可解决的问题形式化表述如下: \min_{x}f(x)\\such \ that \begin{cases}c(x)&\le&0\\ceq(x)&=&0\\A\times x&\le&0\\ Aeq \times x&=&0\\ lb ...
Create an optimization problem with obj as the objective function. Get prob = optimproblem('Objective',obj); Create a nonlinear constraint that the solution lies in a tilted ellipse, specified asxy2+(x+2)2+(y−2)22≤2.Create the constraint as an inequality expression of the optimization...
在MATLAB中,遗传算法GA工具箱可以求解带约束的非线性多变量函数(Constrained nonlinear multivariable function)的最小值,即可以用来求解非线性规划问题。今天主要是以实际的例子详细讲解遗传算法GA工具箱求解非线性规划。 MATLAB中,非线性规划模型的写法如下: 基本语法 [x,fval] = ga(fun,nvars,A,b,Aeq,beq,lb,ub...
The interior-point approach to constrained minimization is to solve a sequence of approximate minimization problems. The original problem is (33)For each μ > 0, the approximate problem is (34)There are as many slack variables si as there are inequality constraints g. The si are restricted to...
Hi, I am optimizing my system design using MATLAB GLOBAL OPTIMIZATION TOOLBOX.i used GA and it worked well.Now i am trying to use another technique to compare and verify the results. My objective function is nonlinear constrained type and I am trying to use SA.But SA doesn't have ...
