Constraint algebra

Constraint algebra is a mathematical framework that focuses on the study and manipulation of constraints, which are conditions or limitations placed on variables in a mathematical model. Generally, it is used in optimization, database theory, artificial intelligence, and various fields of mathematics and computer science. ### Key Concepts in Constraint Algebra: 1. **Constraints**: Conditions that restrict the values that variables can take. For example, in a linear programming problem, constraints can specify that certain variables must be non-negative or must satisfy linear inequalities.
