Backtracking is one algorithm which can be used to implement nondeterminism. 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. There are also several similar words to Backtrack in our dictionary, which are Back. Backtracking terminates when there are no more solutions to the first sub-problem. Backtrack is an verb (used without object) according to parts of speech. 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. 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.
BACKTRACK MEANING SERIES
A scheme for solving a series of sub-problems each of which may have multiple possible solutions and where the solution chosen for one sub-problem may affect the possible solutions of later sub-problems.Teacher: 'Dear students, stand up if you think you are stupid. Derived forms: backtracked, backtracks, backtracking There is relatively little information about backtrack, maybe you can watch a bilingual story to relax your mood, I wish you a happy day Bilingual Reading Of The Day.
