1. Log on to one of the teaching machines:
lab110-5 ... lab110-18
2. Set cplex's environment variable.
If you are using tcsh or csh then your environment should
setenv CPLEXLICDIR /usr/local/pkgs/cplex/licdir
If you are using Bourne shell then your environment should
CPLEXLICDIR=/usr/local/pkgs/cplex/licdir; export CPLEXLICDIR
3. Make sure your search path include /usr/local/bin.
4. Just type "cplex" and you should get the cplex prompt.
5. Our licence only allows 10 users at any one time.
6. Complete documentation is in the consultants office at the labs in McConnell 106.
7. A few sample cplex input files are contained in http://cgm.cs.mcgill.ca/~avis/courses/software/cplex
8. Here is a sample session on sita for the 5 queens problem:
