Dijkstra's algorithm adapted for robot navigation with provable guarantees

Researchers have developed a novel approach to online stochastic shortest path navigation for mobile robots, leveraging Dijkstra's algorithm under specific conditions. The proposed DORA (Dijkstra Oracle Reduced-cost Algorithm) learner utilizes a shortest path oracle a fixed number of times per episode, avoiding the need to estimate transition kernels. Numerical experiments demonstrated that DORA matches optimistic value iteration in performance across various benchmarks while significantly reducing computational work and minimizing contacts with dynamic obstacles.
