I fully agree, having been looking into the same papers. It also doesn't help that each author start out with their own version of the basic implementation which often won't match the implementation the other authors use.

I think I finally managed to get the SPPF to get the right structure now, but it is way harder to penetrate compared to the complexity of the underlying idea.

Now I only have to figure out how to actually iterate over the different parse trees..
