in reply to Schedule Optimization

This is clearly a data modelling problem - even if you do find a module that provides some kind of assistance, it wouldn't be flexible enough to handle those 'other constraints' nor can it remotely address the risk of design change your requirement represents.

My advice is that before even deciding what to implement in perl or SQL, you need to design and maintain your logical data model (here is a short course and use that to drive what you then build in perl, DDL and/or SQL as your physical implementation.

At that point you'll have well-definied entities we can look at to advise on how to implement them.

Your requirement does suggest the event entity would be a parent that owns event-day children (as database tables) but I'd need to see the rest of the requirement to be confident about that - also I don't yet see why you want to use mathematical combinations which are different from the simple multiples concept your requirement so far suggests

Hope this helps,
