June 22 2002 2:43:32.282 PM CVT_BASIS Arrange a set of PDE solution data into clusters. Null cluster policy: 0, do nothing, accept null clusters; 1, reset center to a random data point; 2, reset center to random point in hull; NULL_CLUSTER_POLICY = 0 RANDOM_INITIALIZE Initialize RANDOM_NUMBER with user SEED = 12345678 What is the run type? RUN_TYPE = 8 For RUN_TYPE = 8, read in the steady state solution from "STEADY.TXT" and, letting SS be the steady state solution, subtract 5/3 SS from solutions 1 through 250 subtract 1/3 SS from solutions 251 through 500. We DROP the odd numbered solutions. We do NOT normalize the result. What is the name of the XY data file? The file "/math/WWW/f_src/cvt_basis_cavity/xy.txt" contains 1681 lines. X minimum : 0.00000 X maximum : 1.00000 Y minimum : 0.00000 Y maximum : 1.00000 What is the name of the steady state file? Steady state information was read from the file "/math/WWW/f_src/cvt_basis_cavity/steady.txt". Steady max norm = 3.00000 Steady l2 norm = 33.7950 What is the name of the first solution file? We believe the number of solution files is 500 The data is stored in an M by N matrix. The "spatial" dimension M is 3362 The number of data points N is 500 All the data has been read into POINT. RUN_TYPE = 8: Thin out the input data points. Thinning increment is 2 Original input data size is 500 Thinned data size is 250 Enter lower and upper number of clusters The program will try to determine the minimum energy of a clustering, for cluster sizes in the range: 4 4 Enter the number of different random cluster configurations to check For each number of clusters, the number of distinct initial random configurations to be checked will be 15 Enter the number of energy iterations For each initial random configuration, the number of times the program will recompute the cluster centers, cluster components, and energy is 30 Enter 0 to use raw data, 1 to use normalized data. NORMAL = 0 Data will NOT be normalized.
