 Hierarchical constraint satisfaction

Hierarchical constraint satisfaction refers to a specific approach within the broader field of constraint satisfaction problems (CSPs) that organizes variables, constraints, and solutions in a hierarchical manner. In general, a constraint satisfaction problem involves finding assignments to a set of variables such that all constraints on these variables are satisfied. ### Key Features of Hierarchical Constraint Satisfaction: 1. **Hierarchy of Constraints**: In this approach, constraints are organized into different levels of importance or specificity.
