Howdy, Passing along this question about Math::GSL here, since this list is more appropriate. Duke ---------- Forwarded message ---------- From: Filipe G. Vieira <fgvieira@berkeley.edu> Date: Mon, Jan 23, 2012 at 10:44 AM Subject: GSL mnultimin To: jonathan@leto.net, thierry.moisan@gmail.com Hi, I've just found your perl module to run GSL::multimin. I'm trying to use that functions in C++ but I have a doubt that, despite not related to the perl module, I thought you might be able to help me with. I want to limit the search space to [0,1] but the GSL function has no limit option. I tried to implement myself and I came up with two alternatives but I don't know if they are the best options. One is to just return a high score whenever the parameter goes out of the interval: if(gsl_vector_get(0,i) < min || gsl_vector_get(x,i) > max) return 1e100; The other is to set the parameter to 0: if(gsl_vector_get(0,i) < min) x->data[0] = min; if(gsl_vector_get(0,i) > max) x->data[0] = max; Are these approaches correct? Which one is the best? Any better way to do it? thanks, FGV -- Jonathan "Duke" Leto <jonathan@leto.net> Leto Labs LLC 209.691.DUKE // http://labs.leto.net NOTE: Personal email is only checked twice a day at 10am/2pm PST, please call/text for time-sensitive matters.
