In the area of graph theory in mathematics, a signed graph is a graph in which each edge has a positive or negative sign. A signed graph is balanced if the product of edge signs around every cycle is positive. The name "signed graph" and the notion of balance appeared first in a mathematical paper of Frank Harary in … See more The sign of a path is the product of the signs of its edges. Thus a path is positive only if there are an even number of negative edges in it (where zero is even). In the mathematical balance theory of Frank Harary, … See more Frustration index Give each vertex a value of +1 or −1; we call this a state of Σ. An edge is called satisfied if it is … See more There are two matroids associated with a signed graph, called the signed-graphic matroid (also called the frame matroid or sometimes bias matroid) and the lift matroid, both of … See more A vertex-signed graph, sometimes called a marked graph, is a graph whose vertices are given signs. A circle is called consistent (but this … See more Three fundamental questions about a signed graph are: Is it balanced? What is the largest size of a balanced edge set in it? What is the … See more Sometimes the signs are taken to be +1 and −1. This is only a difference of notation, if the signs are still multiplied around a circle and the sign of the product is the important thing. However, there are two other ways of treating the edge labels that do not fit into … See more As with unsigned graphs, there is a notion of signed graph coloring. Where a coloring of a graph is a mapping from the vertex set to the natural … See more WebInference on Image Classification Graphs. 5.6.1. Inference on Image Classification Graphs.

Web1 Introduction. A signed graph G ˙ is a pair (G, σ), where G is an (unsigned) graph (V, E), called the underlying graph, and σ: E {1, − 1} is the sign function or signature.The order of G ˙, denoted by n, is the number of its vertices.The edge set of G ˙ consists of positive and negative edges determined by σ.We interpret a graph as a signed graph whose signature …
