Arc Consistency Consider the problem of arranging the schedule for an event. There are three time slots: 1, 2, and 3. There are three presenters: A, B, and C. The variables for the CSP will then be A, B, and C, each with domain {1, 2, 3}. The following constraints need to be satisfied: 1. A, B, and C all need to take on different values 2. A 1. Enforce consistency for the arc A-C, and then write which values remain for each variable
2. Starting from the result of the previous step, enforce consistency for the arc B--A, and then write which values remain for each variable.
3. Starting from the result of the previous step, enforce consistency for the arc C-A, and then write which values remain for each variable.
