Sequential Timeline
Order days as Monday→Sunday. Map constraints: 'earlier than', 'before', 'neither first nor last'.
Valid schedule: Monday:Hina, Wednesday:Ira, Thursday:Rhea, Friday:Zoya, Sunday:Bhavya
Use inequalities to form partial orders and then linearize.
Verification:
- Hina's talk is earlier than Bhavya's.
- Rhea's talk is neither first nor last.
- Ira's talk is before Zoya's.
