The General Pattern

Explore the fundamental pattern of backtracking algorithms, focusing on how to design recursive solutions that make consistent sequential decisions based on past choices. Learn how to efficiently build problem-solving structures by managing decision history in C++.

Characteristics of backtracking algorithms

Backtracking algorithms are commonly used to make a sequence of decisions, with the goal of building a recursively defined structure satisfying certain constraints. Often (but not always), this goal structure is itself a sequence. For example:

  • In the n
