Subject: Transportation LP for PC

Does anyone have any information on the availability of transportation LP
software for PCs? I am making this enquiry for a colleague who is a
statistician.

Thanks for any leads,

Subject: Multi-dimensional Runge-Kutta code in C

A friend of mine is looking for a multi-dimensional Runge-Kutta
code written in C: till now we have found the pseudo-code
given in "Numerical Software Tools in C" by James Kempf.
Has anyone other suggestions?

Many thanks.

I am happy to announce the publication of my book:

Volker L. Mehrmann

The Autonomous Linear Quadratic Control Problem: Theory and Numerical Solution

Lecture Notes in Control and Information Sciences, Vol. 163, Springer Verlag
Heidelberg,

In this book a survey is given on the state of the art in  theory and
the numerical solution of general linear quadratic optimal control problems
with differential algebraic equation constraints. This field is very active
in the last ten years and in particular the step from standard ordinary
differential equation constraints to differential algebraic equation
constraints has received a lot of interest. Although the theory for the
standard case is known since the sixties the development of numerical methods
is not complete. For the descriptor case this is even more the case.
Here not even the development of the theory can be considered near to complete.
On the other hand these problems occur in many applications, in particular in
engineering and it is therefore important to have a solid mathematical theory
as well as reliable numerical algorithms.
For this reason we review and extend theory and numerical methods for these
problems together and we hope that this book helps increase
the cooperation between pure mathematicians, numerical analysts and practioners.

Subject: University of Waterloo Technical Reports

The Department of Computer Science at the University of
Waterloo (Canada) would like to announce the formation
of its technical reports archive.

To access the archive, ftp to "cs-archive.uwaterloo.ca".

Reports are indexed by report number (as subdirectories)
in the directory "cs-archive".  The file "README" gives
you more information about how to download tech reports.
The file "Index" gives a list of the tech reports currently
available.  Not all our tech reports are available via ftp
at this moment, but it is our intention to make all future
reports available.

Reports are generally stored as compressed version of
.dvi or .ps files, and should be downloaded using the
"binary" option of ftp.  Once downloaded, you will
probably have to use "uncompress".
