[Help-glpk] Increase PL speed

[Lucio Barreto]

Helloanyone.

 

I have implemented a
branch-and-bound by myself, using the GLPK lpx_simplex()
routine to solve each linear problem I have.

 

I want to know if anybody
knows some  #8220;best practices #8221; to increase the speed of my PLs?

I am already using:

 

lpx_set_int_parm(lp, LPX_K_PRESOL, 1);

lpx_warm_up(lp);

lpx_simplex(lp);

 

Thanks a lot.

 

Regards,
