Description : Several C-language codes for n * n matrix multiply, n a
              power of 2, developed as a laboratory exercise in the
              Spring of 1993 for MIT course 6.891, "Source Code
              Optimization for Workstations and Supercomputers."  The
              sources are commented, however the recursive SRM
              (shuffled-row major) algorithm is obscure.  Offered "as
              is" into the public domain by the course instructor.

Language    : C
Systems     : Unix (DOS if getopt available)
Description : Piecewise finds a piecewise linear approximation to a
              1D function. The program provides two methods to find
              the approximating segments, both satisfying an L infinity
              error norm and both SUB-OPTIMAL. The user specifies the
              tabulated function values and an error bound and the program
              returns the endpoints of the line segments that approximate the
              function. The operation is fast (essentially a single pass
              through the data) and works reasonably well on data with
              low noise. If the noise level is too high an alternative
              approach using smoothing splines should be used.

              and man pages.  Explicitly designed to work with Unix
              philosophy.  The file stat.tar.Z.crypt.uu is ENCRYPTED;
              you have to send email asking for the password.
              There is a handbook available.

Name        : SVDPACKC.tar.Z
Where       : in pub/berry on cs.utk.edu
Systems     : Sun, IBM RS/6000, HP9000, DECstation, Macintosh II/fx, Cray Y-MP
Language    : C
Description : an ANSI-C library for the singular value decomposition
            : of large sparse matrices.  Lanczos- and subspace iteraton-
            : based methods are used to iteratively compute several
            : of the largest (or smallest) singular values and corres-
            : ponding singular vectors.  Sample  UNIX C-SHELL scripts
            : are provided for automatic compiling and testing of the
            : library routines.   Cray Y-MP compatible routines provided.

Version     : 1.0, June 1993

Systems     : Any C environment
Description : Simple heuristic Travelling Salesman Problem solver
Author      : Dan Kegel - from "Discrete Optimization Algorithms," Maciej Syslo
Version     : 1.1

Name        : tsp_solve

Systems     : Borland, sco and Sun with gcc
Language    : C++


              like to test their own TSP tour finder's performance
Version     : 1.0beta
Description : Finds Optimal and Heuristic Solutions to many types of
              Traveling Salesman Problems (TSP).
Comments    : tsp_solve finds optimal solutions to geometric TSPs with 100
              cities in about an hour (don't go to lenscrafters for this one.)
              It will soon have an asymmetric TSP optimal solution finder that
              will perform at approximately the same level.

Version     : 3.0 (soon to be 3.1)
Description : visualizing/animating data made by numerical weather
              models and similar sources
Comments    : vis5d interactively provides 3-D isosurfaces, vector-field
              slices, horizontal and vertical contour and colored slices,
              and ribbon "particle" trajectories (integral curves)
