reachability analysis

Reachability analysis is a method used to determine whether a system, such as a robot or software program, can arrive at a certain state or position from its starting point, given its possible actions and constraints. It helps identify all the possible scenarios or conditions a system can reach over time. This analysis is valuable for ensuring safety, verifying correctness, and understanding behavior, especially in complex systems like autonomous vehicles or control systems. Essentially, it maps out the "reachable" configurations to prevent errors or failures.
