Heuristic-seeded NSGA-IIA+D · meets all 17 benchmark constraints. Brief B0043
Plan drawing of a courtyard on a 19.9 by 25.6 metre lot, 2 storeys, 4 dwellings, 25 rooms. Dwelling U0 (1BR) has 5 rooms totalling 77 square metres. Dwelling U1 (2BR) has 6 rooms totalling 76 square metres. Dwelling U2 (2BR) has 6 rooms totalling 77 square metres. Dwelling U3 (2BR) has 6 rooms totalling 76 square metres. Building footprint 176 square metres; open space 331 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.62, daylight 0.69, privacy 0.79, circulation 0.62, carbon 0.71, cost 0.45.
