Heuristic-seeded NSGA-IIA+D · meets all 17 benchmark constraints. Brief B0023
Plan drawing of a triplex on a 13.5 by 27.4 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 91 square metres. Dwelling U2 (2BR) has 6 rooms totalling 146 square metres. Building footprint 158 square metres; open space 205 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.97, daylight 0.51, privacy 0.77, circulation 0.76, carbon 0.83, cost 0.63.
