generate several scenarios and compare optimization result

Hi all

i am doing optimization with genetic algorithm. i have n number of variables x=[x1, x2, x3,....xn]

X is calculated by eq: xn = Prop(n)/ Pmcr

i want the algorithm to make the following two scenarios,

for every (x < 0.3 )

scenario.1: replace it with (0) and complete the code until the end, and store the output value of fitness function as one of the solution

scenario.2: replace this x with (Prop(n) + Elec / Pmcr) and also go through a sequance of different operations until the end of code

both scenarios are to be excuted and compared by the optimization algorithm
