Graph-theoretic clustering
WebAn Introduction to Graph-Cut Graph-cut is an algorithm that finds a globally optimal segmentation solution. Also know as Min-cut. Equivalent to Max-flow. [1] [1] Wu and … WebA novel graph theoretic approach for data clustering is presented and its application to the image segmentation problem is demonstrated, resulting in an optimal solution equivalent to that obtained by partitioning the complete equivalent tree and is able to handle very large graphs with several hundred thousand vertices.

WebIn this paper, we present some graph theoretic results relating various parameters. We use them in order to trace some algorithmic implications, mainly dealing with the fixed-parameter tractability of the problem.
