Planning Via Random Walk-Driven Local Search

The RW-LS planner Arvand-LS is described Most successful current satisficing planners combine several next, followed by a section about the generation and selection complementary search algorithms. Examples range from of harder problems from existing IPC domains for portfolio planners such as Fast Downward Stone Soup which scalable problem generators are available. The experimental (Helmert, Röger, and Karpas 2011) and loosely coupled parallel results for Arvand-LS show strong improvements planners such as ArvandHerd (Valenzano et al. 2011) to over the state of the art in both coverage and plan quality for systems which alternate several search strategies, such as FF hard problems from several IPC domains. The paper concludes (Hoffmann and Nebel 2001), FD (Helmert 2006), and ArvandHerd, with a discussion of possible future work, including and dual queue search algorithms as in LAMA perspectives for a portfolio system containing Arvand-LS.
