Webb14 juni 2024 · Simulated Annealing or SA is a heuristic search algorithm that is inspired by the annealing mechanism in the metallurgy industry. Annealing refers to a controlled cooling mechanism that leads to the desired state of the material. But, how does this map to an optimization problem? Webb22 maj 2024 · Answers (1) Generally speaking, simulated annealing can be used to solve QAP, but it would likely be much much slower than a routine designed for solving QAP. simulannealbnd supports bounds constraints, but no other kinds of constraints, and it does not support anything like event functions that might provide constraints.

Simulated annealing can also be applied to problems like yours, in which the adjutable parameters are continuous. My advice is to use fmincon () to minimize your function. You said you are trying to "optimize" myf (x).
