Abstract

One of the important features of an interconnection network is its ability to efficiently simulate programs or parallel algorithms written for other architectures. Such a simulation problem can be mathematically formulated as a graph embedding problem. In this paper, we embed complete multipartite graphs into certain trees, such as \(k\)-rooted complete binary trees and \(k\)-rooted sibling trees.

Keywords: Embedding, wirelength, complete multipartite graphs, binary tree, sibling tree
