I found the paper to be very explicit, given that the authors are not in Universities. They explained their algorithms from both an equational and an algorithmic approach, and I think they provided enough details to replicate the algorithm.
I am a little suspicious about their results. They briefly describe the competition methods. This would be fine if these methods are well-known and not ambiguous, but my suspicion is that they did not spend much effort making sure the algorithms were performing as well as they could.
