I want to know how to apply boundary limits for the equation . I want to optimize the Bead Volume using genetic algorithm code

I want to submit my project within 2 days please send the code Bead volume = 0.5+0.016x1+0.14x2-0.077x3+0.030x4-0.00075x1x2-0.00325x1x3+0.035x1x4+0.11x2x3+0.034x2x4-0.022x3x4-0.063x12-0.13x22+0.00455x32-0.028x42

You have three equations and limits for the independent variables, but nobody knows what you are supposed to do ...
