They're 2 algorithms or 'concepts' used in computing. A* is an evolution of Dijkstra's original shortest path algorithm, used by both games and most existing navigation software. It assumes prior knowledge of all aspects of the terrain to be navigated and an ideal world without pedestratians and other cars. It is only of minor relevance in the use case of autonomously navigating a road or parking lot.I am curious to learn more about R*/A* algorithm. Can you tell me a bit more about what it is and how it relates to enhanced summon? Thanks.
R* refers to a method for indexing (geo)spatial information in a way that makes it accessible/usable for other algorithms to operate on. While likely a very relevant foundation for how EAP/FSD works in Tesla's software it is not even remotely a good-to-go solution for autonomously navigating a road or parking lot.
So, both are very low level building blocks for the pretty phenomenal software Tesla builds on top of them, and the poster you're responding to is just a troll. He's more or less saying it's not impressive if one can run 100m in 6 seconds because humans have had legs for thousands of years.
