bipartite

C# Many To Many Relationship

So, I need some way to implement an undirected network ( I think this is the correct term ) in C# Let's say I have the following data: Foo1 <-> Bar1 Foo2 <-> Bar1 Foo2 <-> Bar2 Foo2 <-> Bar3 Foo3 <-> Bar2 Foo3 <-> Bar3 How would I implement something that could support this? One way to do this would be to create a class containing ...

How do I partition a bipartite graph by color?

For instance, suppose I have a graph G = (V, E) where V = {A, B, C, D} E = {(A, B), (A,D), (C, D)} This graph is bipartite, and thus can be split into two disjoint sets {A, C} and {B, D}. My first guess is that I can simply walk the graph and assign alternating colors to each vertex. Is this the case, or is it more complicated/simple...

Bipartite matching in Python

Does anybody know any module in Python that computes the best bipartite matching? I have tried the following two: munkres hungarian However, in my case, I have to deal with non-complete graph (i.e., there might not be an edge between two nodes), and therefore, there might not be a match if the node has no edge. The above two packag...

How do I implement a Bipartite Graph in Java?

UPDATE Some answers so far have suggested using an adjacency list. How would an adjacency list look like in Java? ... no pointers right :) I'm trying to implement a Bipartite Graph in Java to sort into 2 groups information from a file. I found this example and it actually does the job: http://users.skynet.be/alperthereal/source_file...

Maximum weight bipartite matching

I have a graph in form of a rectangular grid, i.e. N nodes and 2N edges, all adjacent nodes are connected. This means it is two-colourable, and hence it is possible to do bipartite matching on it. Each (undirected) edge has a weight assigned to it - either -2, -1, 0, 1 or 2. No other values are allowed How would I go about finding the ...
