Problem $4$:

Write a MATLAB$/$Python code to find the best possible solution $($maximum$)$ within $10,000$

iterations:

$f(x_1,x_2,x_3)=3x_1^2+2x_2^2+x_3^2-2x_1{x}_2+2x_2{x}_3-2x_1{x}_3-6x_1-4x_2-2x_3$

$x_{1}in[-5,5],x_{2}in[-3,3],x_{3}in[-1,6]$

Please provide your codes and print the $f(x),x_1,x_2,x_3$ for every five hundred iterations, e$.$g$.,$

$1,500,1000,$dotsdots,$1000.$
