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...

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-...
K-匿名[1]是一种简单而有效的隐私保护模型,实施K-匿名要考虑两个方面:(1)确保数据发布过程中隐私不泄露;(2)发布的匿名数据具有实用性。 基于以上两个要求,众多学者提出了许多匿名算法。但大体上可以分为全域泛化算法[2]和局域泛化算法[3]。相比之下,局域泛化算法不仅可以实现K-匿名,而且一定程度上降低了匿名...
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...
We present two single exponential linear timeFPTalgorithms, one forCollapsed k-Corewithk= 1 and one fork= 2. In both cases the parameter is (b+x). In particular, the algorithm fork= 2 runs inO(1.755x+ 4b⋅n) time which means that it solvesFeedback Vertex SetinO(9.487b⋅n) ti...
