Backtracking, английский
A method used in search algorithms to retreat from an unacceptable position and restart the search at a previously known "good" position. typical search and optimization problems involve choosing the "best" solution, subject to some constraints (for example, purchasing a house subject to budget limitations, proximity to schools, etc.) a "brute force" approach would look at all available houses, eliminate those that did not meet the constraint, and then order the solutions from best to worst. an incremental search would gradually narrow in the houses under consideration. if, at one step, the search wandered into a neighborhood that was too expensive, the search algorithm would need a method to back up to a previous state.
