The maximal ,-dependent set problem for planar graphs is in NC,d a maximal subset . of . such that no vertex . has degree>.(.) in the subgraph induced by .. Whether the problem is in . (or .) or not is an open question. Concerning this question, only a rather trivial result due to Diks, Garrido, and Lingas is known up to now, which says that the problem can be

Dominoes,ow that they can be recognized in linear time, give a linear time algorithm for listing all maximal cliques (which implies a linear time algorithm computing a maximum clique of a domino) and show that the PATHWIDTH problem remains NP-complete when restricted to the class of chordal dominoes.

Minimum vertex cover, distributed decision-making, and communication complexity,re . is the number of processors. In the second framework two processors are allowed to communicate in order to find an approximate solution: in this latter case, we show a linear lower bound on the communication complexity of the problem.

Our proof of this is based on the theory of partitions of integers and is the first non-trivial lower bound on the number of obstructions for treewidth.
