I've been testing the bfgs2 minimizer, and it works well until/if it
nears a point in which the interpolator stops progressing - I've
noticed there is a check against this in the linear_minimize code near
line 209:
if ((a-alpha)*fpa <= GSL_DBL_EPSILON) {
/* roundoff prevents progress */
};
perhaps there should be a break statement to prevent futile
iterations? Or use this as a stopping criteria test?
