To do:

~~condition equivalent to hypergraph acyclicity~~ this is said in tree clustering; move above?
clique-width
computing width and decomposition (cost, LOGCFL)
~~other structural restrictions~~: anything to add?
~~algorithms for the resulting acyclic problems:~~ something else to be mentioned here?

Is the decomposition-example correct? "For every edge of the original graph, there is a node that contains both its endpoints": z,w are connected in the original graph, but no node exists in the decomposed graph that contains both z and w. Also, shouldn't it be "u,x,y" on the left side? Perhaps I misunderstood hypertree decomposition, it would be nice if someone else could take a look at this.
