Detailed Description
file reader for cycle clustering instances
This file implements the reader for the cycle clustering problem. The data is read from a matrix, entries separated by whitespace. The first line in the file has to be of the form "# p nstates ncluster", where nstates is the size of the matrix and ncluster is the number of clusters that should be used. The file has to have the ending ".cyc" to be recognized by the reader.
