- 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.

 - 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.
