An SPQR tree takes the form of an unrooted tree divjding which for each node x there is associated an undirected graph or multigraph G x. By using this site, you agree to the Terms of Use and Privacy Policy.

However, for a planar graph with labeled vertices and edges that is 2-connected but not 3-connected, there may be greater freedom in finding a planar embedding.

graaph In graph theorya branch of mathematics, the triconnected components of a biconnected graph are a system of smaller graphs that describe all of the 2-vertex cuts in the graph. Additionally, in a P node of the SPQR tree, the different parts of the graph connected to virtual edges of the P node may be arbitrarily permuted.

Each edge xy between two nodes of the SPQR tree is associated with two directed virtual edgesone of which is an edge in G x and the other of which is an edge in G y. Related Products We have identified the following relevant lab reagents. All planar representations may be described in this way. When a component is found in s way, a stack data structure is used to identify the edges that should be part of the new component.

Views Read Edit View history. CiteULike organises scholarly or grqph papers or literature and provides bibliographic which means it makes bibliographies for universities and higher education establishments. Each vertex in one of the graphs G x may be associated in this way with a unique vertex in G Tthe supervertex into which it was merged.

With this assumption, the SPQR tree is uniquely determined from its graph. This page was last edited on 16 Mayat You can also specify a CiteULike article id.

Whenever SPQR tree edge xy associates the virtual edge ab of G x with the virtual edge cd of G yform a single larger graph by merging a and c into a single supervertex, merging b and d into another single supervertex, and deleting the two virtual edges.

They then find a special preorder numbering of the nodes in the tree, and use certain patterns in this numbering to identify pairs of vertices that can separate the graph into smaller components.

The SPQR tree of a graph may be constructed in linear time [1] and has several applications in dynamic graph algorithms and graph drawing. There are no reviews of this article.
