I use Octave 7.1.0 with ga 1.10.3 on windows 10 64x.
ga *| 0.10.3 |
C:\Octave\Octave-7.1.0\mingw64\share\octave\packages\ga-0.10.3
The one variable simple problem below gave a wrong answer. x=0 is output. The
correct result should be x=LB.
LB/UB appear to be ineffective. I have not found any document to indicate if
there are limitations on ga function.
pkg load ga
fun=@(x) x.^2
x0=1.75; LB=1; UB=2;
ga_options = gaoptimset('Generations', 100, 'PopulationSize', 30,
'InitialPopulation', x0, 'Vectorized', 'off');
[x, fval, exitflag, output, population, scores] = ga (fitnessfcn=fun, nvars=1,
A=[], b=[], Aeq=[], beq=[], LB, UB, nonlcon=[], ga_options);x % x =
-1.9613e-11 or some other near zero values
Thanks,
