Why this formula appears here
The planner underneath Shakey was STRIPS — the Stanford Research Institute Problem Solver — described by Fikes and Nilsson in a 1971 paper in the journal Artificial Intelligence . STRIPS represented the world as a set of predicate-logic statements, represented each available action as an operator with a precondition list, a delete list, and an add list, and used a resolution theorem prover guided by means-ends analysis to search for a sequence of operators connecting the current state to a goal state [ 2 ] . Formally, for a state s represented as a set of ground predicates and an operator a with precondition set , delete set , and add set , the…
