Design a floorplan for a two-bedroom, one-bathroom apartment

Living room should face north-west

The two bedrooms should not have a common wall

At least one of the bedrooms should have direct access to the bathroom

Experimental Setup Authors and two colleagues evolved floorplans Individually Collaboratively Ten computer science graduate students evaluated the designs by taking a survey The plans were evaluated for creative content based on practicality and originality
