State space search is a process used in the field of computer science, including artificial intelligence (AI), in which successive configurations or states of an instance are considered, with the intention of finding a goal state with the desired property. Problems are often modelled as a state space, a set of states that a problem can be in. The set of states forms a graph where two states are connected if there is an operation that can be perform… WebJun 6, 2016 · Defining an Initial state and a Goal Initial stateis a conjunction of ground atoms Goalis as a precondition A conjunction of literals (positive or negative), may contain varialbes: $At(p, SFO) \land Plane(p)$(have any plane at SFO) Variables treated as existentially quantified Planning as a Search problem
