   These diskettes comprise the first five-year tape of algorithms collected
by the Association of Computing Machinary.  These disks were constructed by
copying the original files from the tape onto disk with a minimum of mas-
saging.  The file labeled INDEX contains, oddly enough, a copy of the 
original index (the first file on the tape).

   These routines are a collection of FORTRAN routines/procedures for solving
a variety of problems in science, engineering and numerical analysis.  There
are routines for the solution of zeros of polynomials, various partial dif-
ferential equation solvers, linear equation solvers for over/under-determined
problems (L1, L2 and Chebyshev norms), eigenvalue solvers, function integra-
tion, minimization of unconstrained multivariate functions, curve fitting
in Chebyshev norm, dependence of solution of nonlinear systems on its para-
meters, sorting, global error estimation for ordinary differential equations,
matrix bandwidth and profile reduction, spline interpolation, solution of
linear systems for special matrices, cubic curve fitting using local data,
computation of condition numbers of a matrix without computing eigenvectors,
bessel functions, statistical functions, revised simplex method for 
constrained resource network scheduling, exact solution of integer systems of
linear equations, convex hull algorithm for planar sets, a multiple-precision
arithmetic package, adaptive smooth curve fitting, basic linear algebra
subprograms (BLAS), optimized mass-storage fft, efficient one-way enciphering
algorithm, and more.

   Most, if not all, of these routines were constructed by people under
contract with government agencies.  And so they are very clearly in the
public domain, so you should feel free to share them, but please provide
the originals along with any versions which you've modified.

   The documentation for these routines comes in two forms: "Volume III of
the Collected Algorithms of the ACM" and from journals.  The former is 
obtainable from the ACM and the latter may be found in any good university
library.  The address of the ACM is 11 West 42nd St., New York, New York,
10036.  The book will provide you with details about the implementation of
each algorithm along with references to the literature.  The journals provide
insight into the theory behind each algorithm, as well as more references.

   No effort has been made to port these routines to the IBM-PC.  Since
the authors of these routines have made a concerted effort to write in
"vanilla" FORTRAN, effort has been made to maintain them in the same state
as they came from the tape.  In this way it is assured that previous users
of these programs can utilize them without incurring the additional
overhead associated with "de-porting" them.

   The following is a list of the files (and their sizes) on this disk:

             jbess.fxz     23861  
             knoble.fxz    12113
             leeb.fxz       5577  
             lzhes.fxz      5261  
             mc13d.fxz      3679  
             miller.fxz   113458  
             mini.fxz       8024  
             nikolai.fxz   22342  
             pdecol.fxz    51657  
             pdeone.fxz     2645  
             plib.fxz      33586  
             plm_rakk.fxz   4717  
             profit.fxz     3541  
             qr2noz.fxz     5537  
             quinat.fxz     4801  
             rankci.fxz     7246  
             reduce.fxz     8299  
             read.me        2917
             compress.exe  19017

   To obtain the source file, you must apply the program called "compress"
in the following way: compress -d file.fxz.  This will produce the file
called "file.f" which should then be renamed "file.for".  The source for
"compress.exe" is available separately from PC-SIG.
