Online Saturated Cost Partitioning for Classical Planning

Saturated cost partitioning is a general method for admissiblyadding heuristic estimates for optimal state-space search. Thealgorithm strongly depends on the order in which it considers the heuristics. The strongest previous approach precomputes a set of diverse orders and the corresponding saturatedcost partitionings before the search. This makes evaluatingthe overall heuristic very fast, but requires a long precomputation phase. By diversifying the set of orders online duringthe search we drastically speed up the planning process andeven solve slightly more tasks
