Bliss (charity) a story on neonatal intensive care units. The article said that no hospital had all the equipment it needed to safely care for the premature and sick babies in their care. Allan Chilvers suggested setting up a society to raise funds for life-saving equipment like incubators for premature babies and Bliss (Baby Life Support Systems) was born. In five years Bliss raised £750,000 and donated equipment to 82 hospitals. The 1990s saw the introduction of artificial pulmonary surfactants and antenatal steroids which reduced infant mortality and meant more premature babies began to survive. During this decade, Bliss was chosen as
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.
