Heuristic-seeded NSGA-IIA+D · meets all 17 benchmark constraints. Brief B0001
Plan drawing of a courtyard on a 19.2 by 24.8 metre lot, 2 storeys, 4 dwellings, 24 rooms. Dwelling U0 (1BR) has 5 rooms totalling 83 square metres. Dwelling U1 (1BR) has 5 rooms totalling 83 square metres. Dwelling U2 (2BR) has 6 rooms totalling 83 square metres. Dwelling U3 (2BR) has 6 rooms totalling 83 square metres. Building footprint 184 square metres; open space 292 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.53, daylight 0.65, privacy 0.75, circulation 0.67, carbon 0.73, cost 0.48.
