**Subject: Scientific American January Cover Story**

The cover story in the January 1994 issue of Scientific American

is "Breaking Intractability" by Traub and Wozniakowski. It is shown

that some computationally intractable problems can be solved if one

settles for a good solution on the average. Examples of such problems

are high dimensional integration and approximation.

The current method of choice for computing high dimensional integrals

is Monte Carlo. Preliminary results of software testing by a PhD student,

Spassimir Paskov, indicates that deterministic methods are superior to

Monte Carlo. This testing has been primarily on real-world problems,

of dimension as high as 360, from finance.

We would be grateful to be send other high dimensonal integration or

approximation problems from diverse applications.

**Subject: Help Needed for Coupled PDE and ODE System**

I'm looking for a fortran software package/code that can solve a system

of PDEs and ODEs.

The PDE is a parabolic PDE in one space dimension with known initial and

boundary conditions at x=0.1 and x=1.

par(u)/par(t) = par(par(u)/par(x))/par(x) - f(g(x),m(x),g(x=1),m(x=1))

where f is a function .

m(x) = (u/x + a) where a is a constant

g(x) is the solution of the initial value 2nd order ODE:

2 2

g" + ( m(x) - n(n+1)/x )g = 0

where n is known

and the initial conditons are given

x=0.1 : g(x) = 0

g'(x) = 0

The reason I have not been able to use a standard package to solve this

is because the boundary conditions for the ODE for g(x) are not known.

Any help in solving this system of DE's will be greatly appreciated.

Thanx in advance...

ACCESSING ETNA

BECOMING A SUBSCRIBER TO ETNA.

To be included in ETNA's quarterly mailing list of the titles and abstracts

of papers published in ETNA, send an e-mail message to etna@mcs.kent.edu

with the subject ``ETNA Registration''.

ACCESSING ETNA USING GOPHER.

ETNA is running a gopher server. Its hostname is:

etna.mcs.kent.edu.

If you are running gopher on your system the command

gopher etna.mcs.kent.edu

will connect you directly to ETNA. Provided your system is suitably

configured, keyword searches and the on-line-graphical display of

papers will then be available. The ETNA directory, ``viewers'', contains

the source files for programs that will provide most UNIX workstations

with direct-display and keyword-search capabilities. Contact your system

administrator about installing these programs.

OBTAINING AN ETNA PAPER WITH FTP.

Papers can be obtained at any time from ETNA via anonymous ftp from

etna.mcs.kent.edu. A paper's location will always correspond to

its reference. For instance, a paper which is referenced as

``...,Elec. Trans. Numer. Anal., Vol 1, 1993, pp. 11-32'', will be stored

in the directory ``vol.1.1993'', and its file name will be ``pp11-32.ps''.

To obtain that paper using ftp:

a) ftp etna.mcs.kent.edu

b) login as anonymous

c) enter your e-mail address as your password

d) cd to vol.1.1993

e) get pp11-32.ps

To obtain only the list of titles and abstracts for the papers published

is volume 1 of ETNA, repeat a)-d) above but change e) to

e) get index

OBTAINING AN ETNA PAPER VIA E-MAIL.

ETNA is using a mailer program which will scan incoming e-mail messages

for requests and then e-mail the requested file to the sender. The program

was written by Eric Grosse for netlib and modified slightly by Arden

Ruttan for ETNA.

A PostScript file of any paper published in ETNA may be obtained by sending

an e-mail message to ``mailer@etna.mcs.kent.edu'' containing a phrase of the

form ``send pagenumber.ps from vol.number.year''. For instance, to use

ETNA's mailer to obtain a paper which is referenced as

``...,Elec. Trans. Numer. Anal., Vol 1, 1993, pp. 11-32'',

send e-mail to ``mailer@etna.mcs.kent.edu'' containing the phrase

``send pp11-32.ps from vol.1.1993''.

To obtain only the list of titles and abstract for the papers published

in volume 1 of ETNA, send an e-mail message to ``mailer@etna.mcs.kent.edu''

containing the phrase ``send index from vol.1.1993''.

The requested paper will be e-mailed to you in several pieces. The subject

of each piece of e-mail indicates the number of that piece. To

reconstruct the original file,

a) Edit each piece deleting all lines that are not strictly between

the two occurrence of the phrase ``CUT HERE............''

including the lines containing those phrases.

b) Using the file containing piece 1, successively append

the remaining pieces in order to the END of the that file.

Unix users can also re-assemble the paper by removing the mail headers.

The resulting files are ``sh'' scripts which can reassembled by

issuing the commands (here we are assuming that the various parts

of the papers are stored in ``file1'', ``file2'',...,``filen'').

sh file1

sh file2

.

.

.

sh filen

Unix users may also use the following script which will automatically

reconstruct the original PostScript file.

#!/bin/sh

# This is a shell script which will re-assemble the PostScript file

# mailed to you by ETNA's mailer program. To use this script

# 1) Copy this script to a file in an empty directory and name it reassm.

# 2) Save each mail message from ETNA with a unique name in the

# directory which contains this file.

# 3) Change to that directory and execute the command

# sh reassm

# or alternately you can

# 1) Change to a directory containing this a script in a file.

# 2) Save each mail message from ETNA with a unique name but with a common

# prefix shared by only the ETNA files. For example, you could save the

# respective ETNA files in ff1, ff2, ...

# 3) Assuming the name of this file is reassm, execute the command

# sh reassm ff

ls $1* | grep -v $0 > .f$$

for file in `cat .f$$`

do

echo $file

awk 'BEGIN{i=0};$1=="#!/bin/sh" {i=1};{if (i>0) print $0}' $file > .awk$$

/bin/sh .awk$$

done

rm .f$$

rm .awk$$

SUBMITTING A PAPER TO ETNA.

To obtain information as to how to submit a paper to ETNA, ftp the file

``info-for-authors'' which is located in the directory ``etna-info''.

Alternately you may send an e-mail message to ``mailer@etna.mcs.kent.edu''

containing the phrase ``send info-for-authors from etna-info''.
