An action such as really consists of a long sequence of finer-grained actions: turn on the car, release the brake, accelerate forward, etc. Having composite actions of this kind reduces the number of steps in a solution sequence, thereby reducing the search time. Suppose we take this to the logical extreme, by making super-composite actions out of every possible sequence of actions. Then every problem instance is solved by a single super-composite action, such as . Explain how search would work in this formulation. Is this a practical approach for speeding up problem solving?
