TuGraph-Analytics 已经内置了许多算法,如果想要自定义算法,可以基于AlgorithmUserFunction接口实现,比如自定义k-core 算法实现如下: package com.tugraph.demo; import com.antgroup.geaflow.common.type.primitive.IntegerType; import com.antgroup.geaflow.dsl.common.algo.AlgorithmRuntimeContext; import com.antgroup...
We show its relationship with 3-clique percolation and the k-core algorithm. Finally our experiment results reveal the efficiency of the algorithm and the richer community structure it exposed in real networks.Lu, Chen

K-core is a classic graph algorithm used to calculate the number of cores of each node. The calculation result is one of the most commonly used reference values for determining the importance of a node so that the propagation capability of the node can be better understood. Application Scenario...

Thek-shellis the set of vertices that are part of thek-core but not part of the (k+1)-core. Ifshow_shellsistrue, the algorithm will return the k-shells found for every value of k. within the range provided. For each k-shell, the results will include its member vertices. ...
The resulting subgraph is again the K-Core of the original graph. K-shell decomposition is another algorithm where we initialize the K-shell of the graph to be the set of all vertices with a degree of at least . We then iteratively remove vertices with a degree less than from the K-...
The k-core of a graph may be obtained by use of the k-core algorithm or “the pruning rule”. Remove from the graph all vertices of degree less than k. Some of the remaining vertices may now have less than k edges. Then prune these vertices, and so on until no further pruning is...
