Constraint Networks

Constraint networks are models used to solve problems involving multiple variables and restrictions on their possible values. Imagine planning a schedule where different events cannot overlap and specific resources are limited. Each event is a variable, and the restrictions (or constraints) tell you which events can occur together or how long they can last. By organizing these variables and their constraints in a network, algorithms can efficiently find solutions that meet all the requirements, helping in areas like scheduling, resource allocation, and even puzzle solving.
