Case Study: Autonomous Vehicle Tracking
This real-world inspired scenario models a critical decision-making process for autonomous systems under uncertainty.
Autonomous Vehicle Tracking Scenario
Problem: An approaching plane needs to land while a ground vehicle crosses the runway. The vehicle's movement speed is uncertain (nondeterministic), and its location is tracked by imprecise sensors (probabilistic). The goal is to determine the maximum probability that the vehicle is still on the runway after three time steps, given a sequence of sensor observations.
noDice Approach: noDice models the vehicle's speed choice with nflip() (nondeterministic), sensor noise with flip() (probabilistic), and incorporates sensor measurements using observe() for conditioning. This allows for reasoning about the worst-case scenario across all possible vehicle strategies.
Outcome: By translating the program into a compact Markov Decision Process, noDice accurately calculates the maximum conditional probability (e.g., 3.6% in a specific instance), providing crucial insights for safety-critical systems.
This demonstrates noDice's capability to handle complex interactions between nondeterminism and probabilistic events, which is vital for robust AI applications.
