This code generates a timetable for multiple groups, ensuring various constraints are met. It schedules lectures and practical sessions while avoiding conflicts, synchronizing lectures, and designating free slots.

Tools Used

• Constraints python package: Includes custom constraints for lectures and TD sessions, as well as built-in constraints like AllDifferentConstraint.
• Backtracking Algorithm: Utilized by the constraint library for finding solutions to the CSP.
• Arc Consistency (AC3): Enforced to reduce the search space and improve efficiency, although not explicitly shown in the given code.
