Question

Question3. Consider coloring the map of the southwestern part of the United States, shown at right, with three colors (R, G, B) so that no two neighboring regions that share a border have the same color. We can represent this as a six-variable CSP graph. The states are CA (California), OR (Oregon), NV (Nevada), AZ (Arizona), ID (Idaho), and UT (Utah), and their domain values are determined as {R, G, B}. (a) [5] Draw the condition graph. (b) Apply the [25] tree-structured CSP algorithm on the graph and determine the values that the nodes can take from the domain.

Step 1

The states involved are California (CA), Oregon (OR), Nevada (NV), Arizona (AZ), Idaho (ID), and Utah (UT). The goal is to represent this problem as a constraint satisfaction problem (CSP) and solve it using a tree-structured CSP algorithm. Show more…
