  • evolutionary algorithm — (EA) An algorithm which incorporates aspects of natural selection or survival of the fittest. An evolutionary algorithm maintains a population of structures (usually randomly generated initially), that evolves according to rules of selection, recombination, mutation and survival, referred to as genetic operators. A shared "environment" determines the fitness or performance of each individual in the population. The fittest individuals are more likely to be selected for reproduction (retention or duplication), while recombination and mutation modify those individuals, yielding potentially superior ones. EAs are one kind of evolutionary computation and differ from genetic algorithms. A GA generates each individual from some encoded form known as a "chromosome" and it is these which are combined or mutated to breed new individuals. EAs are useful for optimisation when other techniques such as gradient descent or direct, analytical discovery are not possible. Combinatoric and real-valued function optimisation in which the optimisation surface or fitness landscape is "rugged", possessing many locally optimal solutions, are well suited for evolutionary algorithms.

  • john vincent atanasoff — (person)   John Vincent Atanasoff, 1903-10-04 - 1995-06-15. An American mathemetical physicist, and the inventor of the electronic digital computer. Between 1937 and 1942 he built the Atanasoff-Berry Computer with Clifford Berry, at the Iowa State University. Atanasoff was born on 1903-10-04 in Hamilton, New York. In 1925, he got a Bachelor of Science degree in Electrical Engineering from the University of Florida. In 1926 he received a Master's degree in Maths from Iowa State University. He received a PhD as a theoretical physicist from the University of Wisconsin in 1930. While an associate professor of mathematics and physics at Iowa State University, Atanasoff began to envision a digital computational device, believing analogue devices to be too restrictive. Whilst working on his electronic digital computer, Atanasoff was introduced to a graduate student named Clifford Berry, who helped him build the computer. The first prototype of the Atanasoff-Berry Computer was demonstrated in December 1939. Although no patent was awarded for the new computer, in 1973 US District Judge Earl R. Larson declared Atanasoff the inventor of the digital computer (declaring the ENIAC patent invalid). Atanasoff was awarded the National Medal of Technology by US President Bush on 1990-11-13. He died following a stroke on 1995-06-15.
