- 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.

- historical materialism — (in Marxist theory) the doctrine that all forms of social thought, as art or philosophy, and institutions, as the family or the state, develop as a superstructure founded on an economic base; that they reflect the character of economic relations and are altered or modified as a result of class struggles; that each ruling economic class produces the class that will destroy or replace it; and that dialectical necessity requires the eventual withering away of the state and the establishment of a classless society: the body of theory, in dialectical materialism, dealing with historical process and social causation.

- instruction scheduling — The compiler phase that orders instructions on a pipelined, superscalar, or VLIW architecture so as to maximise the number of function units operating in parallel and to minimise the time they spend waiting for each other. Examples are filling a delay slot; interspersing floating-point instructions with integer instructions to keep both units operating; making adjacent instructions independent, e.g. one which writes a register and another which reads from it; separating memory writes to avoid filling the write buffer.

Wall, "Available Instruction-Level Parallelism for Superscalar and Superpipelined Processors", Proceedings of the Third International Conference on Architectural Support for Programming Languages and Operating Systems, pp. 272--282, 1989.
