treelength

tags: tree decomposition

Definition: Treelength of a tree decomposition is the maxmimum distance of two vertices that appear in the same bag. Treelength of a graph is the minimum treelength over tree decompositions.

Results

assumed
- diameter upper bounds treelength by a linear function – By definition
- treelength is equivalent to treelength – assumed
