Open in MATLAB Online Hello everyone, I run my code and got this error " Failure in initial user-supplied objective function evaluation." I don't know how to solve it. Hope you can help me, Thank ThemeCopy function y=annealing(x,C,P,T,R) y=log(x(1))+x(2)*log(...
how to solve this error? Objective function is returning undefined values at initial point. FSOLVE cannot continue.The objective function supplied to 'fsolve' must return a vector without any Inf or NaN entries.In
Minimizing an objective functionUnless you place some further constraints on W values, there is no limit to how much 'f' can be reduced. The right answer would be minus infinity. For example, let W(1) = 1, w(2) = +2^50, w(3) = -2^50. Then the sum of the w's is 1 and ...
