Backtracking Basics

Backtracking is an algorithmic technique for solving problems recursively by trying to build a solution incrementally, one piece at a time, removing those solutions that fail to satisfy the constraints.

State Space Search

Think of it as exploring a tree where each node is a decision. If a path leads to a dead end, you "backtrack" to the previous node and try a different branch.
