An empirical route was followed through the use of stochastic simulations and comparisons with traditional truncationselection. Repeated cycles of directional and truncationselection are practised. These procedures are more efficient than standard truncationselection. When the effective size is considered, the predictions are good, suggesting that the effect of the deviations from normality is small under truncationselection. A suitable fitness function, drawn over the number of trimer repeats, may be of the synergistic epistatic or truncationselection type. In order to avoid this reduction of long-term gain, multi-generation optimization of truncationselection schemes is needed. We shall now consider truncationselection in which individuals with the largest phenotypic values are selected. With truncationselection across genotypes, differences between truncation points for the three genotypes are equal to differences between means of the distributions. By contrast, under truncationselection, there was no clear distinction between selective advantages in their relationship with contributions. Yet the optimal allocation of weights is based on deterministic predictions for the gain with standard truncationselection. Under truncationselection, the distribution of the genetic variance along the chromosome can be computed by numerical integration of (4). However, this is not the case for the frequency distributions of a^sel, for which, even under truncationselection, some overlapping can occur between selected and unselected candidates. Additionally, at selection time, the probability that a selected candidate had an equal or greater a^sel than an unselected candidate was greater with quadratic optimization than under truncationselection. Hill (2002) studied the effect of truncationselection on phenotype on changes of mean and phenotypic variance. Taking the best half, third or another proportion of the individuals is truncationselection. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Truncationselection is less sophisticated than many other selection methods, and is not often used in practice.

Contrast this with a less sophisticated selection algorithm, such as truncationselection, which will eliminate a fixed percentage of the weakest candidates.
