Heuristics and Search for Domain-Independent Planning (HSDIP)

State-space search guided by heuristics, automatically derived from the problem representation, has been one of the most popular, and arguably one of the most successful, approaches to domain-independent planning in the last decade. While there has been significant developments in the design of planning heuristics, such that there are now many different kinds of heuristics, and some theories of how they relate to each other have begun to emerge, there is also a growing realisation that the search algorithm plays an equally important role in the approach. Recent work has highlighted some of the weaknesses of some search algorithms, but also the rich opportunities for exploiting synergies between the heuristic calculation and the search to improve both, drawing on the fact that domain-independent planning offers a declarative description of the state space (not just a "black box" successor function).

The workshop on Heuristics and Search for Domain-Independent Planning (HSDIP) follows in the tradition of the "Heuristics for Domain-Independent Planning (HDIP)"  workshop series that was held at ICAPS 2007, 2009 and 2011. However, since the number contributions to the workshop relating to search (not just heuristics) has steadily grown, the ICAPS 2012 workshop widens the scope to explicitly encourage work on search for domain-independent planning.
