Abstract

See full text

A method for partitioning a group of cells in a network into a set of disjoint blocks of cells. The network is represented by a hierarchical graph with each level representing a hierarchy of resources, leaf nodes representing the blocks of cells, and edges representing interconnections between resources. A gain matrix is formed by combining a gain vector for each level of hierarchy for each possible move. Cells are moved between leaf nodes based on the gain matrix computed.
