for X = SIMULANNEALBND(FUN,X0,LB,UB)， the vector X0 starts the point finding so that the answer LB<=X<=UB. How if i want to add a certain condition to vector X, say exp(X(1)+X(2))<X(3)?
Another word to say besides the X must in between LB and UB, X has to fulfill the condition as well.
Simulated Annealing does not allow for non-linear constraints, it only allows bound constraints. Hence simulannealibnd.
If you have non-linear constraints such as the one you shared in the questions, you can use GA instead
