Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Machine Learning with PHP? Challenge accepted!
There's nothing stopping PHP using the GPU other than nobody having written bindings to the appropriate libraries. Compare https://github.com/RubixML/Tensor for example, which provides bindings to LAPACK and OpenBLAS and will already provide a massive speed boost for linear algebra operations. They aren't GPU accelerated, but all* that's needed is a similar extension with (e.g.) cuBLAS bindings.

Phalcon Roadmap
Note that this particular technique has been used by our friends at RubixML and it works just fine.

Genetic Algorithms in PHP
Interesting solution! I think you'd find the code would run a lot faster if you built up a node-map of the distances between each node rather than calculating this at every step. I've got a Genetic Algorithm library that allows for abstractions, which completes in about 10s. You'd also find better response times running this on the command line rather than using a browser for this. Great work though!

Machine Learning with PHP? Challenge accepted!
Yeah agreed, I wrote an example Genetic Algorithm library (https://github.com/nathansalter/genetic-algorithm/blob/master/examples/tsp.php) years and years ago, worked absolutely fine with a reasonable execution time. I would say that for any workload that's CPU bound PHP is just as good as any other language. Memory bound problems often have better languages for performance.
