kkentzo / pso Goto Github PK

Hi,I use Ubantu to run your pso code,I've already set on gsl.But there is still a bug in pso.h-264:

// allocate the RNG
settings->rng = gsl_rng_alloc(gsl_rng_default);

Error message is : identifier "gsl_rng_default" is undefined.

Hey,
I'm learning PSO these days and your library has been extremely helpful in clarifying some doubts I had. However, I see that you use sqrt (i + 1) in the Griewank Function definition, whereas the actual definition uses sqrt (i).

When i use sqrt (i) in my implementation, it always elicits -nan, but yields a value when sqrt (i + 1) is used. Why did you use sqrt (i + 1)?

Regards

Hi,
Sorry to bother you, I'm a newbie so hopefully my question won't make you unconfortable.

I want to try to merge your PSO function into mine, what I want to do is using PSO to find optimal parameters of GMM which can differentiates foreground object from background.
But my question is can I use your PSO function without GSL library? I find that you use GSL for random number generation. Is that necessary to use GSL? Or could I just use rand() in C ?

Thanks for your help.

Could you please implement separate boundaries for each variable in the code?
This could be very useful for many problems which require
separate limitations for the variables involved.

Thanks in advance,
