Bliss (charity) weeks gestational age. This study is helping to inform healthcare and education services to ensure the right support is provided at all times for premature and sick babies as they grow towards adulthood. The heads of babies that are born extremely premature (less than 29 weeks) do not grow very well, which affects how their brains develop later. Many of these babies are fed intravenously, directly into a vein, in the first month of life as their gut is too immature to digest milk in high enough quantities for their nutritional needs. The SCAMP study, which was funded by Bliss,
Premature convergence presumed or hypothesized causes for the occurrence of premature convergence. Rechenberg introduced the idea of self-adaptation of mutation distributions in evolutionary strategies. According to Rechenberg, the control parameters for these mutation distributions evolved internally through self-adaptation, rather than predetermination. He called it the "1/5-succes rule of evolutionary strategies" (1 + 1)-ES: The step size control parameter would be increased by some factor if the relative frequency of positive mutations through a determined period of time is larger than 1/5, vice versa if it is smaller than 1/5. Self-adaptive mutations may very well be one of the causes for premature convergence.
