This is because soft selection tends to use all the information available, while hard selection loses some additional information by selecting only a subset of the antenna elements.
Our analysis of selective mortality on SAH indicated that hard selection could be adequately modeled by a two-parameter logistic function (α = 1.430, bootstrap 95% CI: 0.997, 1.883; β = 0.272, bootstrap 95% CI: 0.095, 0.462), which suggested that hard selection on SAH was predominantly directional (Fig. 3A).
What followed in such systems can be thought of as a hard selection sweep in which alleles associated with residency were selected to a much greater frequency than the same alleles in the migrant population.
We extrapolate selection at one site in two years to an entire drainage, extrapolate selective mortality beyond the bounds of our empirical data, and assume hard selection wherein frequency and density-dependent effects are not factored.
They didn't do that with mediocre players, making the Tottenham Dream Team a particularly hard selection.
This would be Dale Steyn's spot but he only played five Tests this year, so it became the hardest selection in the XI.
He has never been afraid to take hard selection decisions, as he did before Britain's semi-final against Australia when he dropped James Ward, a hero against the United States in the first round, in favour of Dan Evans, who had all but disappeared off the British radar.
Whether it's the overly generous swath of inventive original trick weapons, the three new yet eerily familiar environments, the advancement of the game's already cryptic lore or the brutally hard selection of new boss fights, The Old Hunters is a nigh-on perfect addition to a modern classic.
Results indicate that soft selection always outperforms hard selection.
(b) When, neither soft nor hard selection seems effective.
