This book gives workable ideas that will help preachers capture and maintain the interest of their listeners without sacrificing the spiritual content of their message.

Implementations of two effective matrix reordering algorithms were published in this paper as Algorithms 508, which implements the Gibbs-Poole-Stockmeyer algorithm for reducing the bandwidth of a matrix, and 509, which implements the Gibbs-King algorithm for reducing the profile of a matrix. Reduction of matrix profile is more often required than bandwidth reduction, but Algorithm 509 is substantially slower than Algorithm 508. Consequently, the Gibbs-Poole-Stockmeyer algorithm has been recommended and used in contexts where the better profile reduction provided by the Gibbs-King algorithm would be more appropriate. In addition, Algorithms 508 and 509 both contain unnecessary restrictions on problem size and provide little error checking. The authors describe a new FORTRAN implementation of both reordering algorithms which is portable, faster, more reliable and uses less storage than the original implementations. The new implementation of the Gibbs-King algorithm is much faster than Algorithm 509, generally slightly faster than Algorithm 508 and nearly as fast as the new implementation of the Gibbs-King-Stockmeyer algorithm.
