profit of alternative selection methods at the nucleus and multiplier tiers, measured at grow-out level. The selection methods were:
1) rand with random selection from the nucleus to the multiplier and from the multiplier to the grow-out.
2) Trunc_intense with an extremely low truncation selection proportion from the nucleus to the multiplier and a low selection proportion from the multiplier to the grow-out.
3) Rand_Trunc with random selection from the nucleus to the multiplier and truncation selection from the multiplier to the grow-out with moderate selection proportion.
4) Trunc_Rand with moderate truncation selection from the nucleus to the multiplier and random selection from the multiplier to the grow-out.
