## NPTEL AI:Constraint Satisfaction Assignment Answer (week 1) 2023

**1. Select the true statements.**

- A constraint in a CSP is a restriction on the values a variable or a combination of variables can take.
- A solution to a CSP is the set of values assigned to all the variables, such that they satisfy all the constraints.
- A solution to a CSP is the set of values, assigned to some variables, that satisfy some of the constraints.
- In a Binary CSP, each constraint is between two variables.
- In a Binary CSP, the domain of each variable contains exactly two values.

Answer :-A constraint in a CSP is a restriction on the values a variable or a combination of variables can take, A solution to a CSP is the set of values assigned to all the variables, such that they satisfy all the constraints, In a Binary CSP, each constraint is between two variables,

**2. Two constraint networks over the same set of variables are equivalent IF AND ONLY IF __________ .**

- the constraints in the two networks are the same
- the constraint graphs of the two networks are the same
- the matching diagrams of the two networks are the same
- the solutions expressed by the two networks are the same

Answer :-the solutions expressed by the two networks are the same
