Pymoo -Error: Number of values and population size do not match
I have the following set of equations:
x = [x1, x2, x3, x4, x5, x6, x7]
c = [1, 2, 3, 4, 5, 6, 7]
g_cons = [1, 2, 3, 4, 5, 6, 7]
d_cons = [1, 2, 3, 4, 5, 6, 7]
g = Σ(x*g_cons)
d = Σ(x*d_cons)
d_p = d/g*100
e = -0.0038 * d_p * d_p + 0.3501 *d_p –…

possibility of Pymoo to work within a candidate search space
I have a problem of two objective functions, three variables, and zero constraints.
I have also a search space for these variables read from CSV.
Is it possible to use pymoo to use that search space of variables (instead of xl, and xu) to get the…
