Heuristic-seeded NSGA-IIA+D · meets all 17 benchmark constraints. Brief B0065
Plan drawing of a triplex on a 16.4 by 19.0 metre lot, 2 storeys, 3 dwellings, 17 rooms. Dwelling U0 (studio) has 4 rooms totalling 54 square metres. Dwelling U1 (1BR) has 5 rooms totalling 46 square metres. Dwelling U2 (2BR) has 6 rooms totalling 100 square metres. Building footprint 123 square metres; open space 195 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.40, privacy 0.76, circulation 0.57, carbon 0.78, cost 0.60.
