Performance regression for single-order sequence #2361

Closed rhyolight closed 9 years ago

rhyolight commented 9 years ago

NuPIC used to be 100% correct at predicting cellular automata within a 500-element window after 581 rows of data. Now it is only 98.8% correct.

I will try to find out which SHA this started, then I'll probably need to defer to @scottpurdy for analysis.

I think we can update the test since there have been a couple known changes since this test was last run. Here is one case that caused changes: #1972

I've updated it.
