**Subject: Assistance with Knapsack/Assignment Problem**

Dear members of Na_Net,

I would like to request assistance to solve the following problem :

I have i = 1, ...,N satellites and j = 1,...,M ground stations with M > N.

d(i, j) = distance (km) between the satellite i and the ground station j

x(i,j) = 0 if no assignment between the satellite i and the

ground station j

= 1 if assignment between the satellite i and the

ground station j

So the problem is:

Minimizes {Sum_i Sum_j [(d(i,j) * x(i,j)] }

with constraints :

[Sum_i=1_to_N {x(i,j) =< 1} ] for each ground station j = 1,....,M

[Sum_j=1_to_M {x(i,j) = 1} ] for satellite i = 1, ..., N

Actually, I am looking to a code which accept a matrix interface to

define the problem ( and not a classic interface of the linear

programming codes).

Do you have algoritms / codes to solve this problem ?

Free source codes in Fortran (or C ) are mostly convenient, but any other

pointer or reference is also appreciated.

Thanks in advance.

Best regards

**Subject: Faster DFTs than FFTW**

I'm pleased to announce the availability of djbfft 0.70. This version

supports in-place real4, real8, complex4, and complex8 convolution.

djbfft is much faster than FFTW on the Pentium and Pentium MMX. I have

not yet adapted it to other architectures, so it is only a little bit

faster than FFTW on the Pentium Pro and Pentium II.

See http://pobox.com/~djb/djbfft.html for further information.

**Subject: Automatic Differentiation Version of DONLP2**

A new AD version of Peter Spellucci's NLP package DONLP2 has been

released. It uses the TAMC utility of Ralf Giering.

ftp://plato.la.asu.edu/pub/donlp2/donlp2_td.tar.gz

http://plato.la.asu.edu/donlp2.html

Main difference to the previous AD version DONLP2_AD:

- convenient interactive automatic differentiation with included

small script; no implementation of TAMC necessary

- general f77 standard with very few exceptions, no rewriting

of function statements required, no control statements

An online version of DONLP2 can also be accessed via the NEOS Server at

Argonne National Laboratory.

http://www.mcs.anl.gov/home/otc/Server/neos.html

It is intended for testing purposes and accepts input in AMPL. It uses

AMPL's automatic differentiation feature.

**Subject: Multigrid Software Package**

More Efficient Parallelizable MUDPACK

A new version 4.0 of the multigrid software package MUDPACK is now

available on the world wide web. The web site

<http://www.scd.ucar.edu/css/software/mudpack>

includes a detailed description and instructions for downloading

the source code after signing software licensing agreement with the

University Corporation for Atmospheric Research. Since it inception,

portions of MUDPACK have been distributed to hundreds of users from

foreign institutions and within the U.S. The new version was created

to simplify and modernize the package. MUDPACK 4.0 has been passed

through fortran verification software and compiled and executed on

a variety of platforms with both fortran 77 and fortran 90. The

resulting streamlining has yielded code which is more efficient and

more amenable to parallelization than the earlier versions.

MUDPACK 4.0 replaces and is incompatible with earlier versions. The

software includes a suite of portable fortran programs which automatically

discretize and use multigrid techniques to generate second- and fourth-order

approximations to elliptic Partial Differential Equations (PDEs) on

rectangular regions. The elliptic PDEs can be real or complex in two-

and three-dimensions with any combination of mixed derivate, specified, or

periodic boundary conditions. Multigrid V or W cycles which use point,

line(s), or planar relaxation and fully weighted residual restriction are

available for algorithm tuning to obtain optimal multigrid performance.

MUDPACK was written to avoid repeated "re-invention of the wheel" in human

code development time which can be at least as important as saving machine

cycles.

ParMETIS 2.0: A Parallel Graph Partitioning and Sparse Matrix Ordering Library

URL: http://www.cs.umn.edu/~metis

URL: http://www.cs.umn.edu/~karypis/metis

We would like to announce the release of version 2.0 of the ParMETIS library.

ParMETIS is an MPI-based parallel library that implements a variety of

algorithms for partitioning unstructured graphs and for computing

fill-reducing orderings for sparse matrices. ParMETIS is particularly suited

for parallel numerical simulations involving large unstructured meshes.

For these computations, ParMETIS dramatically reduces the time spent in

communication by decomposing the mesh in a way that balances the load and

minimizes the number of interface elements.

ParMETIS's algorithms are based on the multilevel partitioning and fill

reducing ordering algorithms that are implemented in the widely used serial

package METIS. ParMETIS extends the functionality provided by METIS by

including routines that are especially suited for parallel computations and

large scale numerical simulations.

ParMETIS provides the following four major functions:

- Partition an unstructured graph.

- Improve the quality of an existing partition.

- Repartition a graph that corresponds to an adaptively refined mesh.

- Compute a fill-reducing ordering for sparse direct factorization.

Here is a list of the major changes in version 2.0

- Improved support for repartitioning graphs corresponding to adaptively

refined meshes.

* Two new adaptive repartitioning routines have been added that are based

on the remapping paradigm.

* The directed diffusion algorithm has been improved and uses a newly

developed wavefront formulation.

- The number of partitions have been de-coupled from the number of processors.

you can now use the parallel partitioning algorithms to compute a k-way

partitioning independent of the number of processors that are used. This

is particularly useful for parallel computers consisting of clusters of

SMPs.

- The names and calling sequences of all the routines have changed to make it

easier to call the various routines from Fortran.

- The partitioning and ordering algorithms in ParMETIS now utilize various

portions of the serial METIS library. As a result, the quality of the

partitionings and orderings have been improved.

Obtaining ParMETIS

ParMETIS is distributed freely. Information on how to download the source

code is available on WWW at

URL: http://www.cs.umn.edu/~metis

or

URL: http://www.cs.umn.edu/~karypis/metis

ParMETIS has been written by George Karypis, at the Computer Science

Department of the University of Minnesota. If you have any questions or

problems obtaining ParMETIS, send email to metis@cs.umn.edu.

introduced in parallel to the classical theory. The numerical

experiments are used to illustrate properties of differential equations

and theory for finite difference approximations is developed. Numerical

methods are included in the book to show the significance of

computations in partial differential equations and to illustrate the

strong interaction between mathematical theory and the development of

numerical methods. Great care has been taken throughout the book to seek

a sound balance between the analytical and numerical techniques. The

authors present the material at an easy pace with well-organized

exercises ranging from the straightforward to the challenging. In

addition, special projects are included, containing step by step hints

and instructions, to help guide students in the correct way of

approaching partial differential equations. The text would be suitable

for advanced undergraduate and graduate courses in mathematics and

engineering. Necessary prerequisites for this text are basic calculus

and linear algebra. Some elementary knowledge of ordinary differential

A short workshop on "Adaptive Finite Element Methods and Optimization"

will be organized during Nov. 19-21, 1998, at the IWR Heidelberg.

The purpose is to bring together active researchers in this area

and to pick up new and also older ideas for discussion in an informal

and relaxed atmosphere. The focus is on methods for a posteriori error

estimation and economical mesh design in theory and practice.

Applications to real-life problems but also for new proto-typical model

problems are welcome. Particular emphasis can hopefully be put on the

use of adaptive discretization in optimization processes. This seems to

be a developing area with great potential for future research.

Those interested in participating in the workshop should register by

e-mail (afemopt@gaia.iwr.uni-heidelberg.de). The informal deadline

for registration is:

October 16, 1998.

Futher it should be indicated whether a talk will be contributed

(with tentative title). Due to the informal character of the workshop

the program will be determined only shortly before the meeting and will

be handled in a flexible way. The length of talks will be of 20-30

minutes with time for discussion depending on the number of speakers.

Post-Doctoral Research Appointments

The Center for Research in Scientific Computation at N.C. State University

expects to make a number of post-doctoral appointments beginning in the

spring or summer, 1999 (availability of the positions is contingent upon

funding). The appointments, which are typically of at least 2 years duration,

will be in the area of applied mathematics and scientific computation. The

research interests of the Center include mathematical modeling, analysis

and control of partial differential equations, numerical optimization,

computational fluids and flow control, numerical methods for transport in

porous media, stochastic partial differential equations, high-performance

computation and biomathematics .

The successful applicant will become a member of the Center for Research in

Scientific Computation (CRSC), which facilitates interaction between the

faculty in the Mathematics Department and other departments, research

institutions, and industries. The CRSC and the Mathematics Department have

a jointly sponsored Industrial Applied Mathematics Program (IAMP) which is

a formal university/industrial research project program. This program

provides substantive non-academic research-related experiences for graduate

student, postdoctoral, and faculty participants while contributing to the

research efforts of industrial participants. These experiences, involving

year-long participation in an industrial, government lab or agency or other

nonacademic research project, facilitate the development of participants'

ability to communicate and interact with scientists who are not traditional

mathematicians but who have an interest in quantitative aspects of science

and engineering. The program currently has more than 20 graduate students,

**Subject: Postdoctoral Position at CWI-GMD**

In a joint research project of the Dutch Center for Mathematics

and Computer Science (CWI) and the German National Research Center

for Information Technology (GMD), there is an open two- to three-year

position for a POST-DOC.

Research description

Weather forecast and climate models often use spectral or

pseudo-spectral numerical methods for solving the differential

equations that describe the atmospheric motions. Compared to

grid-point numerical methods, e.g. based on finite volumes, such

methods lose their advantage when very fine grids are used.

As a result, there is a renewed interest in grid-point methods

for atmospheric hydrodynamical calculations.

The long term goal of the project is a comprehensive comparison

between newly developed and existing numerical methods, taking

into account the issues of space grid selection and discretization,

use of extremely fine grids, long time integration, and massive

parallelism. The comparison should attempt to answer the question:

which numerical grid-point method is most promising for future

atmospheric hydrodynamical calculations.

During the first half of the project the research will focus on

the shallow water equations on the sphere. These equations may be

considered as a simplified set of atmospheric motion equations.

During the second half, the attention will then gradually shift

to a full set of atmospheric motion equations.

Applicants are expected to have done their PhD research in numerical

mathematics, preferably on PDEs, computational fluid dynamics or in

meteorology with a strong numerical background. Applications from

candidates who are about to finish their PhD-work are also welcome.

Working periods and places will probably be: first half of the

project duration at GMD near Bonn, second half at CWI in Amsterdam.

Prolongation from two to three years will be decided within the

project.

Further information can be obtained from Dr. J.G. Verwer at CWI

(+31-20-5924095; Jan.Verwer@cwi.nl), Prof. U. Trottenberg at GMD

(trottenberg@gmd.de) and Dr. W. Joppich at GMD (+49-2241-142748;

joppich@gmd.de).
