In [[graph theory]], the '''cycle rank''' of a [[directed graph]] is a [[directed graph|digraph]] [[Connectivity (graph theory)|connectivity]] measure proposed first by Eggan and [[Julius Richard Büchi|Büchi]] {{harv|Eggan|1963}}.  Intuitively, this concept measures how close a
digraph is to a [[directed acyclic graph]] (DAG), in the sense that a DAG has
cycle rank zero, while a [[complete graph|complete digraph]] of [[graph (mathematics)#Definitions|order]] ''n'' with a [[self-loop]] at
each vertex has cycle rank ''n''. The cycle rank of a directed graph is closely related to the [[tree-depth]] of an [[undirected graph]] and to the [[star height]] of a [[regular language]]. It has also found use
in [[sparse matrix]] computations (see {{harvnb|Bodlaender|Gilbert|Hafsteinsson|Kloks|1995}}) and [[logic]]
{{harv|Rossman|2008}}.
 
==Definition==
The cycle rank ''r''(''G'') of a digraph ''G''&nbsp;=&nbsp;(''V'',&nbsp;''E'') is inductively defined as follows:
 
* If ''G'' is acyclic, then ''r''(''G'')&nbsp;=&nbsp;0. 
* If ''G'' is [[strongly connected]] and ''E'' is nonempty, then
::<math>r(G) = 1 + \min_{v\in V} r(G-v),\,</math>{{pad|4em}}where G - v is the digraph resulting from deletion of vertex v and all edges beginning or ending at v.
* If ''G'' is not strongly connected, then ''r''(''G'') is equal to the maximum cycle rank among all strongly connected components of ''G''.
 
==History==
Cycle rank was introduced by {{harvtxt|Eggan|1963}} in the context of [[star height]] of [[regular language]]s. It was rediscovered by {{harv|Eisenstat|Liu|2005}} as a generalization of undirected [[tree-depth]], which had been developed beginning in the 1980s
and applied to [[sparse matrix]] computations {{harv|Schreiber|1982}}.
 
==Examples==
The cycle rank of a directed acyclic graph is 0, while a complete digraph of order ''n'' with a [[self-loop]] at
each vertex has cycle rank ''n''.  Apart from these, the cycle rank of a few other digraphs is known: the undirected path <math>P_n</math> of order ''n'', which possesses a symmetric edge relation and no self-loops, has cycle rank <math>\lfloor \log n\rfloor</math> {{harv|McNaughton|1969}}. For the directed <math>(m\times n)</math>-torus <math>T_{m,n}</math>, i.e., the [[cartesian product of graphs|cartesian product]] of two directed circuits of lengths ''m'' and ''n'', we have
<math>r(T_{n,n}) = n</math> and <math>r(T_{m,n}) = \min\{m,n\} + 1</math> for ''m &ne; n'' ({{harvnb|Eggan|1963}}, {{harvnb|Gruber|Holzer|2008}}).
 
==Computing the cycle rank==
 
Computing the cycle rank is computationally hard: {{harvtxt|Gruber|2012}} proves that the corresponding decision problem is [[NP-complete]], even for sparse digraphs of maximum outdegree at most 2. On the positive side, the problem is solvable in time <math>O(1.9129^n)</math> on digraphs of maximum [[outdegree]] at most 2, and in time <math>O^*(2^n)</math> on general digraphs. There is an [[approximation algorithm]] with approximation ratio <math>O((\log n)^\frac32)</math>.
 
==Applications==
 
===Star height of regular languages===
The very first application of cycle rank was in [[formal language theory]], for studying the [[star height]] of [[regular languages]].  {{harvtxt|Eggan|1963}} established a relation between the theories of regular expressions, finite automata, and of [[directed graph]]s.  In subsequent years, this relation became known as ''Eggan's theorem'', cf. {{harvtxt|Sakarovitch|2009}}.
In automata theory, a [[nondeterministic finite automaton|nondeterministic finite automaton with ε-moves]] (ε-NFA) is defined as a [[n-tuple|5-tuple]], (''Q'', Σ, ''δ'', ''q<sub>0</sub>'', ''F''), consisting of
* a finite [[Set (mathematics)|set]] of states ''Q''
* a finite set of [[input symbol]]s Σ
* a set of labeled edges ''δ'', referred to as ''transition relation'': ''Q'' &times; (Σ ∪{ε}) &times; ''Q''.  Here ε denotes the [[empty word]].
* an ''initial'' state ''q''<sub>0</sub> ∈ ''Q''
* a set of states ''F'' distinguished as ''accepting states'' ''F'' ⊆ ''Q''.
A word ''w'' ∈ Σ<sup>*</sup> is accepted by the ε-NFA if there exists a [[directed path]] from the initial state ''q''<sub>0</sub> to some final state in ''F'' using edges from ''δ'', such that the [[concatenation]] of all labels visited along the path yields the word ''w''.  The set of all words over Σ<sup>*</sup> accepted by the automaton is the ''language'' accepted by the automaton ''A''.
 
When speaking of digraph properties of a nondeterministic finite automaton ''A'' with state set ''Q'', we naturally address the digraph with vertex set ''Q'' induced by its transition relation.  Now the theorem is stated as follows.
 
:'''Eggan's Theorem''': The star height of a regular language ''L'' equals the minimum cycle rank among all [[nondeterministic finite automaton|nondeterministic finite automata with ε-moves]] accepting ''L''.
 
Proofs of this theorem are given by {{harvtxt|Eggan|1963}}, and more recently by {{harvtxt|Sakarovitch|2009}}.
 
===Cholesky factorization in sparse matrix computations===
Another application of this concept lies in [[sparse matrix]] computations, namely for using [[nested dissection]] to compute the [[Cholesky factorization]] of a (symmetric) matrix in parallel.  A given sparse <math>(n\times n)</math>-matrix ''M'' may be interpreted as the adjacency matrix of some symmetric digraph ''G'' on ''n'' vertices, in a way such that the non-zero entries of the matrix are in one-to-one correspondence with the edges of ''G''.  If the cycle rank of the digraph ''G'' is at most ''k'', then the Cholesky factorization of ''M'' can be computed in at most ''k'' steps on a parallel computer with <math>n</math> processors {{harv|Dereniowski|Kubale|2004}}.

In graph theory, the cycle rank of a directed graph is a digraph connectivity measure proposed first by Eggan and Büchi Template:Harv. Intuitively, this concept measures how close a digraph is to a directed acyclic graph (DAG), in the sense that a DAG has cycle rank zero, while a complete digraph of order n with a self-loop at each vertex has cycle rank n. The cycle rank of a directed graph is closely related to the tree-depth of an undirected graph and to the star height of a regular language. It has also found use in sparse matrix computations (see Template:Harvnb) and logic Template:Harv.

Definition

The cycle rank r(G) of a digraph G = (VE) is inductively defined as follows:

Template:Padwhere G - v is the digraph resulting from deletion of vertex v and all edges beginning or ending at v.
  • If G is not strongly connected, then r(G) is equal to the maximum cycle rank among all strongly connected components of G.

History

Cycle rank was introduced by Template:Harvtxt in the context of star height of regular languages. It was rediscovered by Template:Harv as a generalization of undirected tree-depth, which had been developed beginning in the 1980s and applied to sparse matrix computations Template:Harv.

Examples

The cycle rank of a directed acyclic graph is 0, while a complete digraph of order n with a self-loop at each vertex has cycle rank n. Apart from these, the cycle rank of a few other digraphs is known: the undirected path of order n, which possesses a symmetric edge relation and no self-loops, has cycle rank Template:Harv. For the directed -torus , i.e., the cartesian product of two directed circuits of lengths m and n, we have and for m ≠ n (Template:Harvnb, Template:Harvnb).

Computing the cycle rank

Computing the cycle rank is computationally hard: Template:Harvtxt proves that the corresponding decision problem is NP-complete, even for sparse digraphs of maximum outdegree at most 2. On the positive side, the problem is solvable in time on digraphs of maximum outdegree at most 2, and in time on general digraphs. There is an approximation algorithm with approximation ratio .

Applications

Star height of regular languages

The very first application of cycle rank was in formal language theory, for studying the star height of regular languages. Template:Harvtxt established a relation between the theories of regular expressions, finite automata, and of directed graphs. In subsequent years, this relation became known as Eggan's theorem, cf. Template:Harvtxt. In automata theory, a nondeterministic finite automaton with ε-moves (ε-NFA) is defined as a 5-tuple, (Q, Σ, δ, q0, F), consisting of

  • a finite set of states Q
  • a finite set of input symbols Σ
  • a set of labeled edges δ, referred to as transition relation: Q × (Σ ∪{ε}) × Q. Here ε denotes the empty word.
  • an initial state q0Q
  • a set of states F distinguished as accepting states FQ.

A word w ∈ Σ* is accepted by the ε-NFA if there exists a directed path from the initial state q0 to some final state in F using edges from δ, such that the concatenation of all labels visited along the path yields the word w. The set of all words over Σ* accepted by the automaton is the language accepted by the automaton A.

When speaking of digraph properties of a nondeterministic finite automaton A with state set Q, we naturally address the digraph with vertex set Q induced by its transition relation. Now the theorem is stated as follows.

Eggan's Theorem: The star height of a regular language L equals the minimum cycle rank among all nondeterministic finite automata with ε-moves accepting L.

Proofs of this theorem are given by Template:Harvtxt, and more recently by Template:Harvtxt.

Cholesky factorization in sparse matrix computations

Another application of this concept lies in sparse matrix computations, namely for using nested dissection to compute the Cholesky factorization of a (symmetric) matrix in parallel. A given sparse -matrix M may be interpreted as the adjacency matrix of some symmetric digraph G on n vertices, in a way such that the non-zero entries of the matrix are in one-to-one correspondence with the edges of G. If the cycle rank of the digraph G is at most k, then the Cholesky factorization of M can be computed in at most k steps on a parallel computer with processors Template:Harv.
