AW: [Help-glpk] Re: How to make consecutive variables take a certain value?

[Gottfried Lindner]

Is it possible to think of a cutting stock problem with day+room as a stock
of a certain length (in hours) and cutting it into lessons with different
lengths?

OK i understand it. But the question now is how to implement a constraint
that 
if an hour is marked as a start time of a session  it is impossible to mark 
as a start time of another session following [sessions's duration - 1 ] 
hours.
