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 jack shaio ------------------------------ Date: Sat, 26 Sep 87 16:41:04 MDT From: Steve McCormick 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.

We are looking for someone in the areas of Large Scale Scientific Computation, Development and Implementation of Algorithms for Parallel and Vector Computers, or related areas of Applied Numerical Analysis. Salary is negotiable. Stony Brook is within commuting distance of New York City with its varied cultural and scientific attractions. Many excellent beaches are readily accessible - one is only ten minutes from the campus. The Stony Brook computing environment includes a state-of-the-art local communications network. The department has seventy-six full time graduate students and produces between seven and eight Ph.D's each year. SUNY is an equal opportunity/affirmative action employer.

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: Global Engineering Documents Incorporated 2625 Hickory St. Santa Ana, CA 92707 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: Public Comment for Dpans Fortran Revision X3 Secretariat Attn: Gwendy Phillips Computer and Business Equipment Manufacturers Association Suite 300 311 First Street, N. W.

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 at: Department of Mathematics, Imperial College, Queen's Gate, London SW7 2BZ, United Kingdom, or electronically, at NA.CASH @ SCORE.Stanford.Edu.

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.
