# homemaker-py-y51: locate the room-count threshold where ruin_recreate
|
||
|
|
# (weight=3.0, homemaker-py-f1d) stops helping. f1d found a clear win on
|
||
|
|
# programme-house (6 rooms, 8W/1L/6T over 15 seeds) but no consistent effect
|
||
|
|
# on harbor-house (37 room instances, 3W/2L/3T, slight negative lean) -- only
|
||
|
|
# two data points, so the size threshold was inferred rather than measured.
|
||
|
|
#
|
||
|
|
# No natural third example programme sits between the two (programme-house2
|
||
|
|
# is the same 6-room size; maple-court is even bigger than harbor-house), so
|
||
|
|
# this sweeps four SYNTHETIC sizes generated from programme-house's own
|
||
|
|
# patterns.config by scaling its b1/t1/b2/t2 bedroom+ensuite module count
|
||
|
|
# (examples/y51-sweep-{10,14,18,22}, see scratchpad gen_sweep.py), holding
|
||
|
|
# room-type mix, storey limits, ratios and adjacency constant -- isolating
|
||
|
|
# room count as the one variable that changes, unlike comparing against
|
||
|
|
# harbor-house's very different programme.
|
||
|
|
#
|
||
|
|
# Same qpk/f1d protocol: paired seeds, --ruin-recreate (weight=3.0, driver.py
|
||
|
|
# _MUTATION_WEIGHTS) ON vs OFF, both arms finish with the default --collapse
|
||
|
|
# (94g), 4 workers. budget=3000 calibrated (see timing probe) to leave
|
||
|
|
# nontrivial residual fails at every size (14/29/27/43 fails at seed 1,
|
||
|
|
# scaling roughly with room count) rather than saturating to ~0.
