Subject: Test Set for Initial Value Problem Solvers

Dear colleague,

Hereby we announce Release 2.1 of the Test Set for IVP Solvers, in
which a number of Initial Value Problems from several application
fields has been brought together. It is available at

The test set consists of a descriptive part and a software part. The
first part describes test problems and reports on the behavior of a
few state-of-the-art solvers when applied to these problems. The
software serves as a platform to test the performance of a solver on
a particular test problem.

With respect to Release 2.0 the following has been changed:

* The formulation of the Chemical Akzo Nobel problem has been
improved. The problem is now an index 1 DAE instead of an ODE.
* The DAE case with full Jacobian and banded mass matrix is now
supported in the DASSL driver.
* The plot of the solution components of the Ring Modulator
problem is now correct.
* A new problem, the Water Tube System, has been added.
* Web server statistics have been added.
* It is no longer possible to submit new test problems.
* Some minor editorial changes have been made in problem

Suggestions and remarks are welcome.

Best regards,

Walter Lioen and Jacques de Swart

Subject: Program Problem in Trujillo and Busby's Book

Dear Colleagues:

I am a beginner to use dynamic programming and regularization method in
inverse analysis. I am looking for help to solve a program problem in
testing an example in textbook

"Practical inverse analysis in engineering"

by David M. Trujillo and Henry Busby

In section 1.5.2 of Chapter 1 (page 20-23), one two-dimension example is
given to show how to combine use of regularization and dynamic program
approach. The results of my program using their method are in agreement with
those given in book for R11, s11, H11, D11, R10 and S10. However, R1 and the
resulting solutions of me are all wrong. Although I have checked my program
with great care, I failed to locate where bugs occur. Now my work stalls
there for nearly one month due to this tiny but fatal difficulty. I also
doubt if there is something wrong with the formulas given in this book.

I hope that someone who used the method of this book can provide me with the
correct results of R9, s9, H9 and D9 of this example so that I can finally
detect the problem in my program.

Also, any information concerning where I can download such program will be
highly appreciated. I also hope to be informed Dr. David M. Trujillo's email
address to ask him to help fix this problem. Anyone who are using this
method are appreciated to provide some opinions and experiences.

Yours sincerely,

Subject: Material for Osborne Symposium Dinner

As advertised previously on na-net, we are hosting
a Two-Day Symposium Honoring the Contributions of Prof.
Mike Osborne to Computational Mathematics. It will take
place this Friday and Saturday, 17-18 of September, at
the Australian National University in Canberra.

In this week leading up to the meeting, I would like
to solicit from members of the Numerical Analysis community
comments, anecdotes, 'best wishes', and the like to be read
at the Symposium Dinner, particularly on behalf of those of
you who might have liked to attend but, understandably, found
the distance rather daunting. So, if anyone would like to
send a note to be read at the dinner, please send them to me
at preferably no later than Thursday
16 September.
