Intractability in Graph Drawing and Geometry: FPT ApproachesThe fixed parameter tractability (FPT) approach pioneered by Downey and Fellows provides an algorithm design philosophy for solving special cases of intractable problems. Here we review several examples from geometry and graph drawing, in particular layered graph drawing, that illustrate fixed parameter tractability techniques.

Unfortunately, a simple counting argument shows that the pointer-based implementation is highly redundant. The number of distinct trees with . nodes is given by the .-th Catalan number:

Studying these trees via generating functions, we show a Rayleigh limiting distribution for expected distances between pairs of vertices in a random .-tree: in a .-tree on . vertices, the proportion of vertices at distance . from a random vertex is asymptotic to ., where ..?=?....
