popsize more than 500 crashes

[dan-ryan]

When I set my popsize on Neat over 500 it crashes when I run neat.evolve(). I'm using the latest version of Node.js and Carrot. The memory with popsize as 500 is only ~100megs, so that doesn't seem to be the issue.

@luiscarbonell You should be able to repeat it easily with the code I gave you.

[dan-ryan]

In my latest changes, it no longer crashes but the generation count doesn't increase, so odd...

[luiscarbonell]

@dan-ryan We've been seeing a lot of these silent failures also.

We're cleaning some of them out with unit testing.

We'll use Mocha and Chai for now.

@christianechevarria Ran into ritewayt by Eric Elliot - but we haven't done extensive work with it yet...

[luiscarbonell]

So far, that we know of, we've cleaned out 7 silent bugs.

[luiscarbonell]

I'll close this for now since we haven't been able to replicate on our end.

[dan-ryan]

Great. I'll test it with the latest code later tonight.

[dan-ryan]

I'm still having generation count issues. Sometimes it works a little higher than a population size of 500 but usually, 2000+ doesn't.

[luiscarbonell]

Will have to create a test where we can increase popsize to Number.MAX_SAFE_INTEGER or Number.MAX_VALUE - ideally.
