Heuristic-seeded NSGA-IIA+D · meets all 17 benchmark constraints. Brief B0068
Plan drawing of a duplex on a 16.9 by 19.4 metre lot, 2 storeys, 2 dwellings, 12 rooms. Dwelling U0 (1BR) has 5 rooms totalling 51 square metres. Dwelling U1 (1BR) has 5 rooms totalling 51 square metres. Building footprint 72 square metres; open space 260 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.30, daylight 0.90, privacy 0.73, circulation 0.53, carbon 0.70, cost 0.25.
