Constraint Programming is a method used in computer science and operations research to solve problems by specifying constraints that must be satisfied. Instead of focusing on how to find a solution, it defines the conditions that any valid solution must meet. This approach is particularly useful for problems involving scheduling, resource allocation, and configuration. In Constraint Programming, variables are assigned values from a defined domain, and constraints limit the possible combinations of these values. The solver explores these combinations systematically, often using techniques like backtracking or propagation to efficiently find solutions that meet all specified constraints.
