[optimization model] Monte Carlo method of optimization calculation

Stochastic simulation is often used to solve global optimization problems . Find the maximum value of the following function .

 

For the sake of understanding , Let's draw first :

clear;
close;
x=linspace(-2*pi,2*pi);
f=(1-x.^3).*sin(3*x);plot(x,f)

  It can be seen that the function is -6
