参数土木工程连续优化问题Based on general ant colony algorithm (ACA) to resolving complex calculation parameters problem in civil engineering, this paper developed a new ACA of intercrossing affected double variable for continuous optimization problem. At the same time, conformed mathematical model and ...
Unrecognized function or variable 'X'. % Calculate costs holding_cost = sum(H .* I); purchase_cost = sum(P .* order_qty); expiry_cost = sum(E .* Sexpired); shortage_cost = sum(B .* C); % Calculate total cost outside the loop ...
I am using symbolic toolbox and fmincon for minimization. But when I am using d, r_g and G_g as symbolic variable I am getting an error. This is the error I am getting "FMINCON requires all values returned by functions to be of data type do...
◆unreachable-code:如果发现从未执行的代码时给出警告。 ◆Inline:如果某函数不能内嵌(inline),无论是声明为inline或者是指定了-finline-functions 选项,编译器都将发出警告。 ◆disabled-optimization:当需要太长时间或过多资源而导致不能完成某项优化时给出警告。 上面是使用-Wall选项时没有生效,但又比较常用的一...

Instead, use one of the unconstrained optimization functions. Their signatures are much shorter than that of fmincon, since they don't accept constraints. 9 Comments Show 7 older comments Steven Lord on 12 Jan 2022 Open in MATLAB Online When I copied...
