Question

There is another (than Bug in the twiddle) bug in the twiddle - the values are not updated even if better are found. Why?

Because old error has a handicap of K factor in the if below:

        print float(err) / float(k+1)
        if err < best_error:
            best_error = float(err) / float(k+1)

I've replaced this with:

        err /= float(K)
        print err

        if err < best_error:
            best_error = err

in lines 625-627, 640-642, and it seems to work fine (the values are updated).
