Module 1 -- Cluster Analysis: Partitioning

Programs require input from amat.dat with a matrix of pairwise dissimilarities/distances and a first line containing the number of objects. User will be prompted for form of matrix, "1" for half matrix and "2" for full n x n matrix. Maximum number of objects is 250. User is also prompted for desired number of clusters. Programs output to results file.

Y Chapter 3 -- Minimum-Diameter Partitioning

bbdiam.for (minimizes maximum within-cluster diamter), bbdisum.for (minimizes sum of cluster diamters) Both programs require the number of partitions to range from 2 to 20)

Y Chapter 4 -- Minimum Within-Cluster Sums of Dissimilarities

bbwcsum.for Number of partitions is limitied to 10. However, a choice of 5 or 6 would be prudent for practical cases.

Y Chapter 5 -- Minimum Within-Cluster Sums of Squares

bbwcss.for Input matrix should contain squared Euclidean distances.

Y Chapter 6 -- Multiobjective Partitioning

bbbiwcss.for Reads a second input matrix, bmat.dat.

Module 2 -- Seriation

Y Chapter 8 -- Dominance Index

bbdom.for

Y Chapter 9 -- Gradient Indices

urg.for, urcg.for, wrg.for, wrcg.for

Y Chapter 10 -- Unidimensional Scaling
