Hi, 

I can #39;t seem to get my head round the expressibility of linear programming. 
I am trying to write a timetabling program using the integer programming 
approach. 
I have 
x[course, day, slot, lecturer, room] as the basic (binary) variable,

How do I express a statement like sum of all assigned (course, day, slot) is 3 
ignoring lecturer and room? Some course may have more than one lecturer... 

I understand that this is a very basic question. Please assist.

Regards,

Benson
