- evolutionary computation — Computer-based problem solving systems that use computational models of evolutionary processes as the key elements in design and implementation. A number of evolutionary computational models have been proposed, including evolutionary algorithms, genetic algorithms, the evolution strategy, evolutionary programming, and artificial life.
- evolutionary programming — (EP) A stochastic optimisation strategy originally conceived by Lawrence J. Fogel in 1960. An initially random population of individuals (trial solutions) is created. Mutations are then applied to each individual to create new individuals. Mutations vary in the severity of their effect on the behaviour of the individual. The new individuals are then compared in a "tournament" to select which should survive to form the new population. EP is similar to a genetic algorithm, but models only the behavioural linkage between parents and their offspring, rather than seeking to emulate specific genetic operators from nature such as the encoding of behaviour in a genome and recombination by genetic crossover. EP is also similar to an evolution strategy (ES) although the two approaches developed independently. In EP, selection is by comparison with a randomly chosen set of other individuals whereas ES typically uses deterministic selection in which the worst individuals are purged from the population.
- explicit type conversion — (programming) (Or "cast" in C and elsewhere). A programming construct (syntax) to specify that an expression's value should be converted to a different type. For example, in C, to convert an integer (usually 32 bits) to a char (usually 8 bits) we might write: int i = 42; char *p = &buf; *p = (char) i; The expression "(char)" (called a "cast") converts i's value to char type. Casts (including this one) are often not strictly necessary, due to automatic coercions performed by the compiler, but can be used to make the conversion obvious and to avoid warning messages.
- exponential distribution — a continuous single-parameter distribution used esp when making statements about the length of life of certain materials or waiting times between randomly occurring events. Its density function is p(x) = λe–λx for positive λ and nonnegative x, and it is a special case of the gamma distribution
