WebMar 24, 2024 · Backtracking is an algorithm used to iterate over all possible solutions in the search space. Therefore, it’s commonly used to solve problems with constraints. In this sense, backtracking limits the search space, thus saving compute time. WebJan 1, 1997 · Chronological Backtracking (BT) [2] is the generic backtracking algorithm. The consistency checks between the instantiation of the current variable and the instantiations of the past variables are performed according to the original order of instantiations. If a consistency check fails, the next domain value of the current variable …
