Heuristic-seeded NSGA-IIA+D · meets all 17 benchmark constraints. Brief B0041
Plan drawing of a triplex on a 15.9 by 25.9 metre lot, 2 storeys, 3 dwellings, 20 rooms. Dwelling U0 (2BR) has 6 rooms totalling 66 square metres. Dwelling U1 (2BR) has 6 rooms totalling 94 square metres. Dwelling U2 (2BR) has 6 rooms totalling 160 square metres. Building footprint 174 square metres; open space 246 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.65, daylight 0.40, privacy 0.79, circulation 0.74, carbon 0.84, cost 0.67.
