Short History


1984 Greuel/Pfister: Existence of complete intersection singularities which are not quasi-homogenous, but Poincare-complex exact?
1987 Pfister et al (Humboldt Uni Berlin): Buchmora for Atari in Modula-2: Existence shown.
1989 Buchmora renamed to SINGULAR; Develloped jointly by groups from Berlin (Pfister) and Kaiserslautern (Greuel); Supported by Volkswagen foundation
1990 Ported to Unix; First user manual
1993 Rewritten in C; SINGULAR programming language -- Libraries; Faster than Macaulay
1996 Multivariate polynomial factorization; gcd
1997 SINGULAR release 1.0 (multivariate polynomial factorization; gcd, syzygies, resolutions, communication links)
1998 SINGULAR release 1.2 (faster, primary decomposition, normalization)
