Algorithm-ArtAnalysis of Bipartite Graph MatchingMany people say that algorithms are an art. But for beginners, I do not have a deep understanding of algorithms, but occasionally feel his strong charm and vitality.This makes it impossible for me to stop pursuing algorithms. Next, I will analyze the Hungarian algorithm and common graph creation methods to enjoy the beauty of the algor
One: Figure of the Classification 1: No direction diagramThat is, there is no explicit pointing relationship between the two vertices, only one edge is connected, for example, a vertex and B vertex can be represented as 2: The MapThe vertices are directional, such as between A and b vertices, a points to the b,b also points to a, the two are different, if the edge is given weight, then this difference is more significant============================================================================
All the objects of the world can be transformed into nodes; all relations in the world can be transformed into a line between nodes, thus forming a graph like fleeting dream. The future of global must be the world of graphs.First, the representation of the figureThe graph has the direction graph and the non-direction graph

Brief introductionPrevious note: TensorFlow study notes 1:get Started We talked about TensorFlow is a computing system based on graph. The nodes of the graph are made up of operations (operation), and each node of the graph is connected by tensor (Tensor) as an edge. So TensorFlow's calculation process is a tensor flow graph
A graph is a flexible data structure that is used to describe the relationship between objects and the connection model.
Algorithms for graphs: minimum spanning tree, shortest path, travel quotient problem, and many other algorithms will be used to breadth-first search and depth-first search , because they provide a set of methods to systematically access graph data structures.
A weighted
Recently in the chapter on the graph theory of discrete mathematics, here is my classification and summary of some important concepts of the graph.
Describe the concept of relationships
Association--used to describe the relationship between a point and an edge, which simply means that the edge is made up of those points and is associated with those points. The correlation matrix is a matrix that records

01 Brief Introduction
The probability graph model is the product of the combination of graph theory and probability theory. It was created by Judea Pearl, a famous one. I like the probability graph model tool very much, it is a powerful multi-variable and visualized modeling tool for variable relations, mainly including two major directions: undirected
Eulerian Graph DetailedA path that passes all the edges once in a diagram ( no map or a forward graph ) and only once across all the vertices in the graph is called the Oraton path , and the loop that passes all the edges once and only once across all the vertices in the diagram is called the Euler loop . A graph with
Graph Cuts is a very useful and popular Energy Optimization algorithm. It is widely used in the computer vision field in image segmentation, stereo vision, and image matting). Graph Cuts theory first appeared in the stream network optimization field, such as water pipe network, communication transmission network, and urban traffic network. In this case, the graph
