GA does not solve problems with integer and equality constraints.

[ploss,v]=power_flow1()

ncap=4;

min=0.1;

max=1;

for i=1:2*ncap

k=mod(i,2);

if k==0

lb(i,1)=min;

ub(i,1)=max;

else

lb(i,1)=2;

ub(i,1)=33;

end

end

Vmin=0.95;

Vmax=1.05

options = gaoptimset;

options = gaoptimset('PopulationSize', 50,'Generations', 500,'StallGenLimit',100,'TimeLimit', 500,'StallTimeLimit', 50,'PlotFcn',@gaplotbestf);

constraints = @(capplcsz_opt) constraint_GA(capplcsz_opt, Vmax, Vmin);

[capplcsz_opt,fval,exitflag]=ga(@power_flow_cap,2*ncap,[],[],[],[],lb,ub,constraints,[1 3 5 7],options);

capplcsz_opt([1 3 5 7])

[ Ploss,Busvoltage]=power_flow_cap(capplcsz_opt)

When I test this code which is shown below. I got an error of " GA does not solve problems with integer and equality constraints." what should I change to solve this problem.

We can neither run your code nor do we have a mathematical description of your problem. So how should we give advice ?
