Note that my method REQUIRES about a gigabyte of RAM to hold the Lexicon and all the working storage, which simply hasn't been available until fairly recently. Before then, other methods WERE faster, because my method couldn't have been crammed into smaller computers. > > My understanding is that Hausser's LA parsers are the fastest mode of > parsing. > > What does Hausser's LA parsing lack that you address? > 1. It works with characters, which Matt's recent test shows to be an order-of-magnitude slower than ordinals. 2.

I eliminate the vast majority of tests that will fail, so that some fraction approaching half will succeed. It will be the SAME tests that succeed with or without my system. I just eliminate the failures. You are apparently working with someone else's opinion that Hausser's method is best, which it may have been when the opinion was rendered. I suggest recruiting the expert who expressed that opinion into this conversation, have him look over what I have written, and then we can have a really productive conversation about this.
