At a glance

This group has too many constraints and lessons to fit into the available schedule.

What causes this error

The combination of all constraints (lesson count, time restrictions, unavailability, room requirements) for this group results in a schedule that is infeasible — there is no way to place all the required lessons.

How to fix it

Review the full configuration for this group:

1. Reduce lesson count — Check if the total lessons can be decreased.
2. Expand time window — Widen the allowed time range (MIN/MAX_TIMESLOT, more working days).
3. Remove restrictions — Identify and relax the most constraining unavailability rules.
