It's behind a paywall but the use of the "commercial" in the title seems weird (the abstract mentions "commercial iterative" technique fwiw). It seems like any kind of algorithm can be commercial and making this part of the comparison is odd. You could have an open source iterative technique or a commercial neural network approach. It's somewhat ironic also they make their code available on github but not the actual article.
