[chapter]
2005
Lecture Notes in Computer Science
Preserved Fulltext
The Satisfactory Partition problem consists of deciding if a given graph has a partition of its vertex set into two nonempty parts such that each vertex has at least as many neighbors in its part as in ...
Similar results hold for balanced partitions where each vertex is required to have at most as many neighbors in its part as in the other part. ...
This problem called Co-Satisfactory Partition corresponds to finding in the graph a maximal cut with respect to moving a vertex from its part to the other. ...

In a balanced (sub)graph, the vertices can be partitioned into two subsets with negative edges present only across the partitions. ...
While existing works have focused primarily on finding the largest balanced subgraph inside a graph, we study the network design problem of maximizing balance of a target community (subgraph). ...

For instance, for the Twitter graph with more than 1.4 billion of edges, our method partitions the graph in about 40 minutes achieving a balanced partition that cuts as few as 6.8% of edges, whereas it ...
Finally, we evaluate the performance gains by using our graph partitioner while solving standard PageRank computation in a graph processing platform, and observe significant gains in terms of the communication ...

We introduce a theoretical and algorithmic framework for multi-way graph partitioning that relies on a multiplicative cut-based objective. We refer to this objective as the Product Cut. ...
The proposed model has strong mathematical underpinnings, and the corresponding algorithm achieves state-of-the-art performance on benchmark data sets. ...
On the other hand Pcut(P) = e −H(P) , which shows that, in the absence of "cut information," the Product Cut will choose the partition that maximizes the entropic balance. ...

The balanced connected k-partition problem consists in finding a connected k-partition in which every class has roughly the same weight. ...
To model this concept of balance, one may seek connected k-partitions that either maximize the weight of a lightest class (max-min BCP_k) or minimize the weight of a heaviest class (min-max BCP_k). ...
The concept of balance of the classes of a connected partition of a graph can be expressed in different ways. ...

For a graph G with e edges and n vertices, our maxcut approximation algorithm runs in O(e + n) sequential time yielding a node-balanced maxcut with size at least (w(E) + w(E)=n)=2, improving the time complexity ...

Maximal k-Color Ordering Problem In this section, we show the NP-completeness of nding the maximal k-color ordering (MCO), and then present an e cient approximation algorithm running in O(e2 k=2 ) time ...
