Hello, In fact, this graph can be represented by a set of cliques . The subsets of tasks that I mentioned in the first message are these clicks. By particular property of this graph, I meant that I don't know if this graph is a perfect graph, chordal graph, interval graph, etc. Thanks! Best regards, ...

Hello, Thank you all for the suggestions. I didn't try overlapLength because I don't know beforehand the length of the overlap of the interval variables. Furthermore, this approach seems to me similar to my use of precedence constraints, i.e., to constrain two interval variables at a time (instead of ...

Hi everyone, I have a scheduling problem in which each task processing sequence and its reverse sequence produce the same objective function value. In this problem, it is possible to eliminate some symmetries by arbitrarily setting one of the tasks to be performed in the first half of the task processing ...
