Graph method: Looking for the Java version __stl/algorithm of the non-graph Unicom subset

In the image processing, the dense method is used, that is, the image is processed by the pixel collection. In the image topology aspect, the graph computation method is applied more. To find a Java version of the non-graph Unicom subset, code: Finds all connected subsets of undirected graphs//wishchin ... public static arraylist Precautions: In

Open source software: NoSQL database-Graph database Cassandra

cite an extreme example. If we have a Cassandra cluster and it's made up of five physical machines. One of the physical machines is 4 times times the capacity of the other physical machines. Then setting the replication factor to 3 o'clock will cause the same data to be stored on a physical machine with a larger capacity. It's not much better than setting it to 2. So in determining the replication factor of a Cassandra cluster, we carefully set an appropriate value based on the number and

Graph database query based on multiple conversion Semantics

1. Summary Because of the complex pattern and different information descriptions of graph databases, it is extremely difficult for non-professional users to query complex graph databases. A Good Graph query engine should support conversion of synonyms, acronyms, abbreviations, and ontology, and should be able to sort search results well. Based on this problem, th

Tags: Things added will also be able to profit create a use maximumWhat is a graphic? A graph consists of two elements: a node and a relationship. Each node represents an entity (person, place, thing, category, or other data segment), and each relationship represents how two nodes are associated. For example, the relationship between the two nodes of cake and dessert is a point from cake to dessert. This versatile structure allows you to simulate a v
