Program to generate the 80 job shop instances proposed by
|
||
|
|
Taillard, E. D.: "Benchmarks for basic scheduling problems",
|
||
|
|
EJOR vol. 64, pp. 278-285, 1993
|
||
|
|
|
||
|
|
Originaly written by Taillard in PASCAL, re-written in C by
|
||
|
|
Dirk C. Mattfeld, University of Bremen <dirk@uni-bremen.de> and
|
||
|
|
Rob J.M. Vaessens, Eindhoven University of Technology <robv@win.tue.nl>.
|
||
|
|
Last update : 2/7/1996.

|
|
UNIX compile: cc -o jsp_gen jsp_gen.c -lm
|
||
|
|
|
||
|
|
Tested on the machines/systems/compilers listed below.

|
|
DEC 5000 Ultrix 4.2 cc

Care should be taken on 64 bit machines (e.g. Cray). There,
|
||
|
|
'long' and 'double' contain 128 bit. In this case replace all
|
||
|
|
'long' and 'double' with the appropriate 64 bit type.
