Hi, I'm using the conjugate_fr algorithm in an optimization problem,
However, after the program executes the function " gsl_multimin_fdfminimizer_iterate (s)" , all the variables "x" (i.e.gsl_vector_get (s->x, k)) and the value of target function (i.e. s->f ) are set to NaN, and they remain NaN in the following iterations. Does anyone know what is the potential problem ? My target function includes digamma fuction, which is taylor approximation of first derivative of the log gamma function. I guess maybe it cause the problem. If anyone who like to help me need my primary code, please contact me! Thanks all, Kevin _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
