Why the Temporary Room Swap Stays

A jamming model of one secondary school's term timetable

A research poster from the School of Emergent Priorities models one secondary school's term timetable as a hard-constraint packing problem and follows 147 room changes entered as temporary. Undoing a swap needs a cascade of other classes moved first, a cascade that grows sharply as room occupancy nears a critical fill; no reversal costing more than three moves was made, and none of the swaps reviewed above 90% occupancy was reversed.
