I added pull request on Github to fix this issue - please check and accept! Thanks :)
In the controls lab in the twiddle.py file the self.params[i] values should not be allowed to go below 0, but code doesn't check for this.
Sometimes when running the algorithm the values can be seen to go below 0.
I added a check if self.params_[i] < 0 then limit value to 0.
