In this geometric setting, two vertices are adjacent if the corresponding points (the disk centers) are within Euclidean distance at most 2 from one. Unit disk graphs are often represented using the coordinates of the disk centers instead of explicit adjacency information. Garey, M., Johnson, D.: Computers and Intractability: A Guide to the Theory of NP-Completeness. A unit disk graph is the intersection graph of nunit disks in the plane. 197, 3–19 (2015)ĭailey, D.P.: Uniqueness of colorability and colorability of planar 4-regular graphs are NP-complete.

The clique definition which requires complete pairwise adjacency in the cluster becomes overly restrictive in such situations.
