[Help-gsl] simplex algorithm for multimin: gsl_multimin_fminimizer_size returns nan

Hi, I'm using the simplex algorithm in an optimization problem, and the program prints the status after each iteration. For some reason the gsl_multimin_fminimizer_size returns nan. Does anyone know what might cause this? How should I debug this? Thanks! -Yong
