Hi Burhan,
From the information shared, I could infer that you are solving an optimization problem with discrete design variables using a custom annealing function. The error message indicates that there is an issue with the function values returned by the custom annealing function, "mynewx". Specifically, the dimensions or types of the output are not as expected. The problem lies in the line where "newx" is updated, as "values(randi(length(optimValues.x)), 1, length(optimValues.x))" results in an incorrect shape for "newx".
To fix this, a single value must be generated from the "values" array for each design variable. Please refer to the below-mentioned corrected MATLAB code for the "mynewx" function:
%Corrected mynewx function
function newx = mynewx(optimValues, ~)
newx = values(randi(length(values), 1, length(optimValues.x)));
end
In this corrected version, "randi(length(values), 1, length(optimValues.x))" generates a row vector of random integers where each integer is between 1 and the length of "values", and each integer corresponds to an index in "values". This vector is then used to index into "values", producing a new array "newx" where each element is randomly chosen from "values".
I hope this helps!
