- A Review of CAS Mathematical Capabilities
by Michael Wester.
From the Abstract:
In this paper, the capabilities of six major general purpose
Computer Algebra Systems (CASs)
(Axiom, Derive, Macsyma, Maple, Mathematica and Reduce)
are reviewed on 123 short problems covering a broad range of
(primarily) symbolic mathematics.
A demo was developed for each CAS, run and the results evaluated.
Problems were graded in terms of whether it was easy or difficult or possible
to produce an answer and if an answer was produced, whether it was correct.

- Comparison of mathematical programs for data analysis
by Stefan Steinhaus.
From the Abstract:
This comparison should give an overview about the functionality,
the availability for different operating systems and the speed of
mathematical programs for analysing huge or very huge data sets in
mathematical, statistical or graphical ways. The focus of this test
is therefor set to mathematical functions which are mainly used
in economics, financial analysis, biology, chemistry, physics and
some other subjects where the numerical analyse of data is very
important.

- PoSSo Examples

- Handbook of Polynomial Systems
by D. Bini and B. Mourrain
The aim of this data base is to provide a consequent list of
polynomial systems which could be used to illustrate,
compare, evaluate different methods for solving polynomial systems.
We will gather polynomial systems (including the list of the
PoSSo project) and add to each of these systems short descriptions
of methods, results of computations, timing, ...

- Record Number Field Sieve Factorisations
by Peter-Lawrence Montgomery.
A team of researchers from Amsterdam and Oregon have factored the
162-digit Cunningham number (12^151 - 1)/11 using the Special Number Field
Sieve (SNFS). This team also factored a 105-digit cofactor of 3^367 - 1
using the General Number Field Sieve (GNFS), These beat the prior records
of 158 digits (SNFS) and 75 digits (GNFS). The Amsterdam group also factored
the 123-digit cofactor of the Most Wanted number 2^511 - 1 using SNFS.

- SATLIB - The Satisfiability Library
by Holger Hoos and Thomas Stuetzle.
From the Abstract:
SATLIB is a collection of benchmark problems, solvers, and tools we are
using for our own SAT related research. One strong motivation for
creating SATLIB is to provide a uniform test-bed for SAT solvers as well
as a site for collecting SAT problem instances, algorithms, and
empirical characterisations of the algorithms' performance.
