From: Jack Shaio <necntc!ci-dandelion!bunny!js07@husc6.harvard.edu>
Subject: C Math Library Needed
To: na@score.stanford.edu
I'm looking for a GOOD (IMSL-like)package of math subroutines,
preferably written in C,
and callable from a C program. My main use is solving nonlinear
equations, and the version of IMSL that we have doesn't implement
the homotopy method.
Does anyone know of other packages available ?
Will they make the accountants scream ?
I need stuff that will run under UNIX, on a VAX 11/785.
Please reply by e-mail, and I'll post a summary to the net.
thanks

Subject: Briggs Tutorial on Multigrid Available from SIAM
To: na@SCORE.STANFORD.EDU
A MULTIGRID TUTORIAL
For those of you who want to get a basic understanding of multigrid concepts
and principles, you should know that SIAM is just about to publish "A Multigrid
Tutorial" by Bill Briggs. This book is a must for those of you who are totally
unfamiliar with multigrid or are uneasy about your current perceptions. The
last chapter should be read by anyone who is interested in obtaining a good
theoretical understanding of multigrid performance. In simple terms, it unifies
the algebraic and spectral theories and gives excellent justification for why
multigrid works so well. Finally, if you're thinking about introducing multigrid
into the classroom, you should consider this book as a possible supplemental
text or resource.
The tutorial is fairly short (about 90 pages) with lots of informative graphs
and illustrations. Best of all, it's cheap: $10.80 for SIAM members, $13.50
otherwise. You can obtain a copy by writing SIAM Customer Service, 117 S. 17th
St., 14th Floor, Phila., PA 19103-5052 or by direct purchase at the October
SIAM meeting in Denver where the price will be $9.45.

Does anyone have the Cooley-Tukey FFT algorithm coded in either C or
Fortran? We have a paper copy of the algorithm on the way, but would
prefer an already coded routine. Thanks,

Subject: Announcement of Fortran 8x
The Public Review Of The Next Draft Proposed Fortran Standard
Begins
Brian T. Smith
Mathematics and Computer Science Division
Argonne National Laboratory
The ANSI Fortran Standards subcommittee X3J3 has completed a
draft of the next proposed standard, informally known as Fortran
8x, and is presenting it for public review. The public review
lasts for four months and is tentatively expected to begin in
early October, 1987. At approximately the same time, the Inter-
national Standards Organization is reviewing the draft proposed
Fortran standard for three months beginning in early November,
1987. The two reviews will thus be completed at roughly the same
time in early February, 1988.
The Fortran community, in particular the numerical community, is
strongly encouraged to review this draft proposed standard. The
document is available from Global Engineering Documents and cost
$50 (U.S.A) if sent to a U.S. address and $65 to an internation-
al address. International orders can be placed at the following
address:

Phone Number (from U.S.A): 1-800-854-7179
Phone Number (outside U.S.A): 1-714-540-9870
This document is written in the form of a draft standard and as
such is not very readable. More readable descriptions are avail-
able and include the following publications. John Reid and Mike
Metcalf have a book titled "Fortran 8x Explained", published by
Oxford University Press. Their book will be available in No-
vember, 1988. The Department of Energy's Language Working Group
has written a paper titled "A Review And Analysis of Fortran 8x",
edited by B. T. Smith, Mathematics and Computer Science Division,
Argonne National Laboratory, 9700 S. Cass Ave., Lemont, Illinois,
U.S.A. 60439. This will be available in late October, 1987.
This proposed Fortran standard has been influenced by the parti-
cipation of several people from the numerical community. These
include: George Paul from IBM Yorktown, John Reid from Harwell,
Lawrie Schonfelder from the University of Liverpool, and Brian
Smith. The new features of particular interest to the numerical
community are the array processing facility, the generalized pre-
cision facility, the environmental inquiry and floating point
manipulation intrinsic functions, internal procedures, new pro-
cedure interface mechanisms, and the new program unit called a
module which permits the sharing of global data and procedures.
I encourage you to carefully consider the proposed standard and
to send comments to the Fortran standards subcommittee X3J3 on
the good and bad aspects of the draft. Comments should be sent
to:

Conference on COMPUTATIONAL ORDINARY DIFFERENTIAL EQUATIONS
Imperial College, London July 3-7, 1989
FIRST CALL FOR PAPERS AND POSTERS
The IMA, jointly with SIAM, is organizing a conference on Computational
Ordinary Differential Equations, to be held at Imperial College, London,
in July 1989.
The aim of this meeting is to bring together research workers and
practitioners in theory and algorithms for the numerical solution of
ordinary differential equations. Contributions from workers in applications
areas will be encouraged. The format of the meeting will be designed to
permit maximum interaction between the participants. The use of
parallel sessions will be minimized and, if practicable, avoided.
The following are the topics to be covered in the conference:
(i) Theory and algorithms for the numerical solution of initial and
boundary value problems in ordinary differential equations,
differential algebraic equations and delay equations.
(ii) Applications areas including the method of lines for partial
differential equations.
(iii) Structured and compartmentalized systems.
(iv) Numerical methods for dynamical systems.
(v) Parameterized and bifurcation problems.
(vi) Impact of supercomputers on numerical methods for ordinary
differential equations.
(vii) Expert systems and graphics in ordinary differential equations.
(viii) Related topics.
The program will include ``highlighted'' papers, contributed papers
and posters. The highlighted papers will be of 40 minutes presentation
time, and contributed papers of 20 minutes presentation time. The
highlighted papers will be selected by the organizing committee
(J. R. Cash, A. R. Curtis, R. England, I. Gladwell and A. Iserles)
on the basis of an extended abstract (1000 words), contributed papers
and posters on the basis of a 300 word abstract. Abstracts for all
categories should be sent to the IMA and must be received by
December 1, 1988. Authors will be notified of the committee's decision
during January 1989.
There will be a reduced conference fee for full-time graduate students.
The proceedings of the conference will be published by Oxford University
Press in the IMA Conference Proceedings Series.
Abstracts and other enquiries should be sent to:
The Secretary and Registrar
The Institute of Mathematics and its Applications
Maitland House, Warrior Square
Southend-on-Sea
Essex SS1 2JY
United Kingdom.
Information can also be obtained from J.R. Cash, either by post

Subject: Pascal Graph Algorithms Sought
The following message is from Kathy O'Hara, a member of the Mathematics
Dept. at the University of Iowa. In sending mail replies, send to her
directly at the University of Iowa, Iowa City, Iowa 52242. For E_mail
replies, send those to NA.ATKINSON.
Ken Atkinson
I'm looking for graph algorithms coded in Pascal. Specifically, the
graph algorithms that appear in Reingold, Nievergelt, and Deo's
Combinatorial Algorithms. I am particularly interested in the algorithms
that, given a graph,
(a) list all of its cycles
(b) finds all maximal cliques
(c) tests for planarity
Any information concerning coded versions of these or other graph
algorithms would be appreciated.
Thanks,
Kathy O'Hara
