Subject: Basis for Linear Equalities

I have the following question to the Numerical Analysis community:

Let C be the set of n-dimensional real vectors satisfying the system
of linear inequalities Ax >= b. By a well-known theorem, every point x
in C is a convex combination of at most n+1 vertices of C (and of at
most n if x lies on the boundary).
Are there efficient algorithms to find such vertices and the corresponding
coefficients?

Subject: Minnesota CS Department Gets New Address
 
We are happy to announce that the Computer Science Dept. at the University
of Minnesota has moved into a nice new big building.  We share the building
with the E.E. Dept.  So far, the building is not all finished, and the
computer network is incomplete.  We are still suffering from moving pains,
but it should turn out to be a fine building, for which we must thank
the State of Minnesota.
 
Therefore, please change your records to reflect our new street address:
 
        Computer Science Dept.
        University of Minnesota
        4-192 EE/CSci Building
        200 Union Street S.E.
        Minneapolis, MN 55455  USA
 
As you can see, we are still in need of a name for the building.
The phone numbers and electronic mail addresses should all be unchanged.

Subject: Frontiers of Science Conference Announcement

                    Frontiers of Science Conference
                            Moscow, U.S.S.R.
                           8-10 December 1988.
   
   The Frontiers of Science Conference to be held 8-10 December in Moscow,
   U.S.S.R., is the sixth in a series of international conferences (two of
   which were forced to be canceled) organized by the Moscow Scientific
   Seminar, a group of Russian "Refusnik" scholars who hold regular
   meetings in the private apartments of group members.  The objectives of
   these conferences are to bring together eminent scientists from diverse
   backgrounds, to provide the members of the Moscow Scientific Seminar
   with an opportunity to communicate with other scientists, and to
   provide seminar members with access to current research results which
   otherwise are denied them.
   
   The seminar members would warmly welcome participants from outside the 
   U.S.S.R.  If you are interested in attending, please call or write
   
             Ms. Dorothy Hirsch,
             Committee of Concerned Scientists,
             330 Seventh Ave., Suite 608,
             New York, NY, 10001, USA.
             Telephone: 212-695-2560.
   
   She can supply you with more information about the conference programme
   as well as travel information and related advice.
   
   (Do NOT contact me for further details about the conference.  I do
    NOT have access to the most up-to-date information.)

Subject: NA-Net Introduction

WELCOME TO NA-Net!

There are several conveniencies associated with NAnet.

1. Sending messages to everyone on the net via the DIGEST.
2. Sending a message to an individual. 
3. Sending a message to SIAM or the AMS.
4. Obtaining software through netlib.
5. Obtaining address information for an individual and/or organization.
6. Distributing and obtaining titles and abstracts from netlib.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% requests, comments or problems to [email-masked]
% submissions for broadcast to [email-masked]
%
% Note: Most people will be able to mail to host "na-net.stanford.edu".  
% However, for those who can't, the mail can be routed through another
% machine: e.g., [email-masked], or
%                [email-masked]
%
% The only people who may have problems getting to na-net are those
% on the Arpa-Internet who are using static host tables rather than
% name resolution software.  I believe that all the major gateways
% to the other nets have good software and there should be no problem
% with mailing from bitnet (netnorth, earn) or csnet sites.  All
% uucp sites that enter the Arpa-Internet through a "good" host
% will also have no problems e.g., rutgers.edu, hplabs.hp.com,
% uunet.uu.net.  This list is not exhaustive.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

A. To send an announcement for the DIGEST,  mail to [email-masked] 
   and everyone on the distribution list will be sent the message.
   To obtain the address list, send the following msg to netlib:
      send nalist from misc

B. To mail to an individual, send a message to 
   na.<last name>@na-net.stanford.edu
   and the message will automatically be forwarded. Try your own name.
   Some addresses are quite complex and/or are not registered so it's
   often easier to use this device.
   If you send a message to 
   [email-masked] that will automatically 
   be sent to me wherever I am. I DON'T GUARANTEE ANY ADDRESS IS CORRECT OR 
   THAT ANY INDIVIDUAL WILL READ HIS/HER MAIL.

C. You can send mail to SIAM simply as [email-masked] or
   [email-masked] and the AMS as [email-masked].

D. You can get some software as indicated below. This effort is due
   to  Jack Dongarra and Eric Grosse. 

E. You can get address information for individuals as indicated below.
   Note the SIAM database is contained in netlib so that you are able to
   get the latest address of a SIAM member. The AMS has not co-operated
   with us on this matter so we cannot provide addresses of AMS members.

F. Richard Bartels (na.bartels) maintains an irregular title and abstract
   distribution service.  He would appreciate electronic notices of
   preprints and technical reports.  Send
    1. title
    2. list of authors
    3. authors' addresses
    4. abstract
    5. means of requesting a copy of the work
   When enough (about 10-15) notices have come in, an announcement
   will be made in the DIGEST and the abstracts can be obtained from netlib.
   
G. Other suggestions are welcome.

H. Please be careful in using the REPLY command. On some systems,
   if "r" is used everyone on the mailing list receives the response;
   a reply with "R" will go to the sender. Do not reply to the Digest!

I. Address any problems to [email-masked].

J. If you want to change your address or if a colleague wants to be on
   the net, send a msg to [email-masked].

K. I keep a data base which is updated from time to time.
   Unfortunately not all the changes have not been included in the
   past. If you want to be included complete the attached form and
   send it to [email-masked]. Note, I've changed the
   form to include FAX numbers. 

< Last Name, First Name>
FNAME               Full name with title.
TITLES              Titles accorded to person.
OADDR               Office address.
OPHONE              Office phone number.
HADDR               Home address.
HPHONE              Home phone number.
PADDR		    Permanent address.
PPHONE		    Phone at permanent address.
INTERESTS           Scientific interests.
FAX 		    Local FAX number.
MISCELLANEOUS       MISCELLANEOUS comments. No special format.

  GENE GOLUB 

You can get mathematical software automatically by electronic mail.
Send mail of the form:
     send qag from quadpack
to one of the three addresses below:
     [email-masked]
     [email-masked]
     research!netlib

"send x from y" gets you the code for routine x in library y 
nd all routines x calls.
To get just x itself, say "send only ...."   You can ask for several
routines at once, and can make several requests, as in the mail:
     send i1mach r1mach from core
     send svd from eispack
     send only ssvdc from linpack

Currently we offer routines from LINPACK, EISPACK, MINPACK, the special
function library FNLIB, the book by Forsythe, Malcolm, and Moler,
QUADPACK, golden oldies (like gaussq), Collected Algorithms of the ACM,
FFTPACK, FISHPACK, QUADPACK, TOEPLITZ, PPPACK (Splines), ITPACK,
BIHAR, and many others including  recent research codes.
To get a table of contents:
     send index
To get an index for a library y, append "for y."

For advice on what routine to try, you still need a numerics expert;
we're just trying to simplify code distribution.  Comments are welcome.

Also, it is possible to get address information on certain individuals.
To do this, use the mail to netlib with the whois command.
For example
      whois meyer 
will  give you the address of more than one Meyer.

(THERE ARE LOTS OF GOODIES IN NETLIB THAT ARE NOT ALWAYS ANNOUNCED! So
it's a good idea to look at the index from time to time --gg)
