A Star (A*) Algorithm with Caching – Java Implementation

Route calculation is computationally an expensive operation. There are several ways how to reduce computational load on the backend. I’ll show you how I optimized my computational resources. There are times where a bunch of people is heading to the same event using the same or at least similar paths. Following this logic, it is ...

A Star (A*) Algorithm Implementation in Java

A* algorithm can be seen as an heuristic extension of Dijkstra’s. Whereas in the Dijkstra’s priority-queue ordering is based only on the distance from the start node to the current, A* algorithm additionally calculates the distance from the current node to the goal-node. Thus the ordering in the priority queue is different and the algorithm ...
