# check, tested on Additive White Gaussian Noise channels with noise standard
# deviations varying from 0.80 to 0.95.

# Testing is done by transmitting random messages, which is safer (though
# slower) than using only zero messages. Decoding is done using a maximum
# of 250 iterations of probability propagation.
