isomorphism

问题 Trying to solve the isomorphic graphs problem here. Assignment info: Determine whether 2 undirected graphs are isomorphic. No isolated vertices. Number of vertices is less than 30 Edges of graphs are given as predicates, i.e. e(1, 2). f(1, 2). I'm trying to use the following approach: For every pair of edges (i.e. for every edge from graph 1 and 2) Try to bind the vertices of 2 edges If binding of vertices is impossible (i.e. another binding with one of the vertex already exists), then

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . I'm working with *.jar files and on graph isomorphism. I want to check for graph isomorphism between two *.jar files. Is there a library for python or ruby for this. Can i do it with igraph or what ? thanks. 回答1:

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . 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 (i.e. is graph g1 isomorphic w.r.t. g2?) subgraph isomorphism test (i.e. is a graph g1 isomorphic to a subgraph of g2?)

问题 Inspired by a question on polymorphic function between ADTs I'm trying to create isomorphisms between multiple (not just 2) types, so that every time I need an isomorphic but not the same type, I can sprinkle my code with some convert . Suppose I have 3 ADTs: data AB = A | B deriving (Show) data CD = C | D deriving (Show) data EF = E | F deriving (Show) Using lens I can implement 2 isomorphisms between AB and CD, and CD and EF: {-# LANGUAGE MultiParamTypeClasses #-} class Isomorphic a b where

问题 Can someone explain the steps of the VF2 algorithm for graph isomorphism in simple words? I am learning this algorithm, but it is harsh without a working example. Can someone lead me the right direction? Thank you. 回答1: I will try to give you a quick explaination of my previous answer to this question : Any working example of VF2 algorithm? I will use the same example as the one in my previous answer : The 2 graphs above are V and V' .(V' is not in the drawing but it's the one on the right)

问题 Right now I'm discovering Este.js and I have a little issue with isomorphic apps. I don't understand how to make api call before rendering server side with renderToString(). One solution consists in doing all the data fetching at the router level using React Router. Depending on the top level route, I can predict which data will be needed, make the api call, and then call React.renderToString. Great, but I still have to declare the data dependencies at the component level AND in the router

问题 can someone show me an example of how to use the Boost Graph Library isomorphism function with vertex invariants? I'm looking at the example at http://www.boost.org/doc/libs/1_50_0/libs/graph/example/isomorphism.cpp, which uses degree_vertex_invariant(). However, I want to define my own invariant function and an example would really help me to understand how to do this. Here are some more details: I am defining a set of discrete attributes on vertices such that I can label each vertex with an
