An optimisation known as " intelligent backtracking" keeps track of the dependencies between sub-problems and only re-solves those which depend on an earlier solution which has changed. This is the algorithm used by logic programming languages such as Prolog to find all possible ways of proving a goal. Backtracking terminates when there are no more solutions to the first sub-problem. If we cannot, or we want all possible solutions, we backtrack and try the next possible solution to the first sub-problem and so on. A backing track is an audio recording on audiotape, CD or a digital recording medium or a MIDI recording of synthesized instruments, sometimes of purely rhythmic accompaniment, often of a rhythm section or other accompaniment parts that live musicians play along with or sing along to. To solve the overall problem, we find a solution to the first sub-problem and then attempt to recursively solve the other sub-problems based on this first solution.
