Unifying Classical Planning Approaches
Subbarao Kambhampati, Biplav Srivastava · 2004
State space and plan space planning approaches have traditionally been seen as fundamentally different and competing approaches to domain-independent planning. We present a plan representation and a generalized algorithm template, called UCP, for unifying these classical planning approaches within a single framework. UCP models planning as a process of refining a partial plan. The alternative approaches to planning are cast as complementary refinement strategies operating on the same partial plan representation.
