My office hours will be Tues and Thurs, 11:30-12:30, until the end of term.

**All classes after Nov. 7 are compulsory!**

**Course software
**

In the course we make use of the packages **maple, lp_solve, cplex **and**
lrs**. All are installed on lab

machines, eg: lab103n-1,2,3 ... . See below for how to get an account.
If you do not find the software,

try typing: %source /usr/socs/Cshrc

**cplex** (path: /usr/local/pkgs/cplex/ )

Instructions for cplex can be found here.

**maple** (path: /usr/local/pkgs/maple/bin/)

A maple session that shows how to solve systems of equations is
here.

This can be useful to check your arithmetic for Assignment 1

This program can be used to solve linear or integer linear programs.

Usage: lp_solve < input_file

Some examples input and output files are here.

The man page is here.

The full package is available for download from the lp_solve home page.

A nice help page with DOS executable is available at:

http://www.statslab.cam.ac.uk/~rrw1/opt/lp_solve/

This program computes all of the extreme points (and extreme rays if any) of the

feasible region of an LP. Home page is: http://cgm.cs.mcgill.ca/~avis/C/lrs.html

How to get a computer account:The prerequisites are

1) Must be taking a
CS course

2) Must have paid tuition

From any unix lab workstation (103N, 105N)

1) Log-in username "newuser"
password "newuser"

2) Follow the steps

- An account will
be created.

Alternative is to use
any webbrowser and connect to

"newuser.cs.mcgill.ca"

Machines are available in McConnell 103n, and have names

lab103n-k.cs.mcgill.ca where k=1,2,3,....

To connect from home you will need to use ssh (telnet will not work)

High performance workstations available for this
course are in MC110, and

have names: lab110-5...lab110-18

The SOCS Inside-Out Website is a dynamic student initiative which aims
to

reduce frustration and raise the level of computing competency
at McGill.

It can be found on the web at http://www.cs.mcgill.ca/~guide.
