Java Code for Contraction Hierarchies Algorithm, A-Star Algorithm and Bidirectional Dijkstra Algorithm. Tested and Verified Code.

. implement Bidirectional Dijkstra and use it to compute distances in social networks very quickly; 2. implement A* search algorithm and apply it to compute distances in road networks faster than the classic algorithms do; 3. implement Contraction Hierarchies algorithm and apply it to preprocess large road networks and then compute distances in …

Serious calibration and benchmarking for the `state_collapser` HRL package

Package implementing recursive pseudo-dimensional reductions of RL state spaces for the synthetic creation of hierarchical reinforcement learning (HRL) training curricula.

Package using state_collapser to give logarithmic speed-up to search for k-simplices in a graph.
