This repo contains code for PSO and its application to a modeling problem. Once you've created libpso.a, you can use it in your own projects. If you cannot count on dynamic linkage to a newish version of GSL, you can statically link it for a more robust binary. Also provided are two RNG modules (one of which must also be compiled in). The header files contain lots of useful documentation. The file model.c is not intended to be reused, but rather it serves to demonstrate the PSO library in action.
To compile:
gcc -std=c99 -O2 -c {pso,transform,util}.c
Add the flag -DEXCLUDE_LINUX to remove dependence on the getrandom() syscall.
ar rcs libpso.a *.o
gcc -std=c99 -O2 -DNT=<number of cores> -c {model,xorshift}.c
Reproducibility from a deterministic generator is not guaranteed for NT > 1. You'll have to tweak model.c to make urandom work and pso.c if you want a custom RNG instead.
gcc -L. -o model {model,xorshift}.o -l{gsl,gslcblas,pso,m} -pthread
