CoCoA:CoCoA 3

About

CoCoA 3 was developed from 1995 (first release) to 2000.

Sub versions

• CoCoA 3.0b (1995)
• CoCoA 3.02b (1996)
• CoCoA 3.3 (1997)
• CoCoA 3.4 (March 1998)
• CoCoA 3.5 (July 1998)
• CoCoA 3.6 (December 1998)
• CoCoA 3.7 (June 1999)

Main Developers

• Antonio Capani
• Gianfranco Niesi

Features

CoCoA 3.0b

• portability (90% of the system is independent of the platform)
• programmability (CoCoAL language)
• arbitrary precision for integer and rational numbers

CoCoA 3.3

Main new features:

• interactive Gröbner framework;
• new algorithms for minimal free resolutions;
• packages;
• new I/O management (devices).

CoCoA 3.4

Main new features:

• ring maps;
• improvement of CoCoAL language;
• univariate factorization over Z;
• computation of toric ideals;
• online help.

CoCoA 3.5

Main new features:

• improvement of CoCoAL language;
• new memory management (simpler way to access variables of different rings);
• autoloading and autoinitializing of packages;
• univariate factorization over Z, Q, and Z/pZ for p prime;
• an updated online help system and an html manual;
• new packages from contributors (integer programming, special varieties, radical).

CoCoA 3.6

Main new features:

• a new package for computations with ideals of points;
• faster computation of Hilbert functions and Poincare series (the POINCARE panel is now unnecessary and so has been disabled);
• a new version of the package for computing radicals of ideals (which now works in greater generality);
• the possibility to have a system-wide Unix/Linux installation.

CoCoA 3.7

Main new features:

• Multivariate factorization over the integers;
• utility functions for modules/vectors (IsTerm, LM, LPP, LPos, Monomials/IsToPos..);
• faster computation of operations on ideals (intersections, saturations,...);
• faster computation of the determinant of matrices with integer entries
• new packages from contributors (algmorph, galois).

A full description of the architecture of CoCoA 3 is presented in Antonio Capani's Ph.D. Thesis (gzipped postscript format).
