There was a problem hiding this comment.
Is advanced version directly based on PhD of Rustam Azimov?

Implemented the CFL Reachability algorithm based on Ilya Muravyov’s approach.
Separated and refactored all optimizations into a seperate file.
Added the core algorithm implementation and comprehensive tests with 100% coverage.
