I have uploaded a new snapshot (rev. 81) to my Solver page. In this release, the most significant change is the support for cell range constraint definition. Well, actually that’s the only visible change since all the other changes are just implementation details.
In my previous snapshot, each constraint entry was used for defining only one constraint. But after some feedback from one user in Belgium I realized that that can be very inconvenient. So I implemented the cell range method. Hopefully I didn’t introduce any new bug with this.
