The Add Building screen provides interface for adding a new building.
Name of the building
External ID of the building (optional)
X and Y coordinates of the building (used in calculating distances between buildings)
Distance between two buildings is computed as Euclidean distance between coordinates × 10 meters (e.g., distance between coordinates [0,0] and [3,4] is 50 meters)
Coordinates cannot be negative
A building with no coordinates is assumed to be too far from any other building (for instructor and student back-to-back constraints)
Note: If you do not have coordinate system established, entering the same coordinates (e.g., [0,0]) for all buildings will ensure that there will be no "too far" instructor and student back-to-back constraint violations in the problem.
