I'm trying to find tool/algorithm for searching sections that corresponds to specified pattern in oriented graph, e.g.: A->B->C or or A<->B->C Please, suggest me direction of my searches. I m...

I create dot file by my perl script. Here is subgraphs which contains same node. eg: subgraph{aa->bb->cc;} subgraph{dd->bb->ee;} I know those subgraph use same namespace, so my result ...

Im a freshman in learning the graph theory. Im learning the (sub)graph isomorphism now. there are two important algorithms: Ullmann's algorithm and vf2. I have read the paper of Ullmann`s: An alg...

I've been struggling with this for a while and cannot seem to find a straight answer. I'm working with compound subgraphs in graphviz and cannot seem to find the right combination of settings to fo...

Subgraph isomorphism is an NP Complete problem. The most widely used algorithm is the one proposed by Ullman. Can someone please explain the algorithm to me in layman's language? I read the ...

I have code to display two subgraphs: graph { rankdir=LR; subgraph cluster01 { label="t=0" a0 [label="A"]; a1 [label="B"]; a2 [label="C"]; a5 [label="E"]; a0 -- a1; a1 -- a2 ; a2 -- a0; ...

I'd like to group some nodes with the following code digraph dataflow { subgraph pipeline { relations; synonyms; articles; } subgraph lucene { index; search; } training_data - > index...

I'm going to start a scientific project about automata and graph theory, and I'm searching for a graph library that supports features like: directed/undirected graphs graph isomorphism test...

Here is an excise for graph. Given an undirected graph G with n vertices and m edges, and an integer k, give an O(m + n) algorithm that finds the maximum induced subgraph H of G such that each v...

I have this Graphviz graph: digraph { rankdir="LR"; overlap = true; Node[shape=record, height="0.4", width="0.4"]; Edge[dir=none]; A B C D E F G H I A -> B -> C D -> E -> F ...

This is what the generated graph looks currently: And here is the code for this: digraph { rankdir=TB; subgraph cluster01 { label="1.fázis" aSTART; node [shape = doublecircle]; a001; nod...

I have an graph with the following attributes: Undirected Not weighted Each vertex has a minimum of 2 and maximum of 6 edges connected to it. Vertex count will be < 100 Graph is static and n...

I'm looking for an algorithm to check whether a given graph is subgraph of another given graph. I have few conditions to make this NP complete problem bit more feasible.. The graphs have approx ...
