Tree Decomposition
Christoph Dittmann

We formalize tree decompositions and tree width in Isabelle/HOL, proving that
trees have treewidth 1. We also show that every edge of a tree decomposition is
a separation of the underlying graph. As an application of this theorem we prove
that complete graphs of size n have treewidth n-1.
