to retract or reverse one’s opinion, action, policy, etc

“retrace one’s steps,” figuratively, by 1896, from literal sense, with reference to hunted foxes, from back (adv.) + track (v.). Related: Backtracked; backtracking.
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.
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. 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. Backtracking terminates when there are no more solutions to the first sub-problem.
This is the algorithm used by logic programming languages such as Prolog to find all possible ways of proving a goal. 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.
Backtracking is one algorithm which can be used to implement nondeterminism. It is effectively a depth-first search of a problem space.
