Parallel Iterative A* Search: An Admissible Distributed Heuristic Search Algorithm
In this paper, a distributed heuristic search algorithm is presented. We show that the algorithm is admissible and give an informal analysis of its load balancing, scalability, an...

On the Value of Good Advice: The Complexity of A* Search with Accurate Heuristics
We study the behavior of the classical A∗ search algorithm when coupled with a heuristic that provides estimates, accurate to within a small multiplicative factor, of the distan...

Structural Patterns of Tractable Sequentially-Optimal Planning
We study the complexity of sequentially-optimal classical planning, and discover new problem classes for whose such optimization is tractable. The results are based on exploiting ...

Learning Heuristic Functions through Approximate Linear Programming
Planning problems are often formulated as heuristic search. The choice of the heuristic function plays a significant role in the performance of planning systems, but a good heuris...
