History of SINGULAR
1984 Greuel/Pfister: Existence of complete intersection singularities which are not quasi-homogeneous, but Poincare-complex exact?
1987 Pfister et al (Humboldt Uni Berlin): Buchmora for Atari in Modula-2: Existence shown.
1989 Buchmora renamed to SINGULAR ; Developed jointly by groups from Berlin (Pfister) and Kaiserslautern (Greuel)
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)
1999 SINGULAR release 1.4 (much faster, numerical data types and algorithms, monodromy, moduli of space curves, debugger)
2001 SINGULAR release 2.0
2002 Book "A SINGULAR Introduction to Commutative Algebra" (by G.-M. Greuel and G. Pfister, with contributions by O. Bachmann, C. Lossen and H. Schönemann). The book includes a CD containing a distribution of SINGULAR version 2-0-3.
