It exists to give every baby born premature or sick in the UK the best chance of survival and quality of life. Its Chief Executive is Caroline Lee-Davey. Bliss was founded in 1979 when a letter was sent to the Daily Telegraph in response to
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.
