  • evolutionary computation — Computer-based problem solving systems that use computational models of evolutionary processes as the key elements in design and implementation.

  • 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.

  • implicit type conversion — (programming)   (Or "coercion") The abilty of some compilers to automatically insert type conversion functions where an expression of one type is used in a context where another type is expected. A common example is coercion of integers to reals so that an expression like sin(1) is compiled as sin(integerToReal(1)) where sin is of type Real -> Real. A coercion is usually performed automatically by the compiler whereas a cast is an explicit type conversion inserted by the programmer. See also subtype.

Instructional technology aims to promote the application of validated, practical procedures in the design and delivery of instruction. It is often defined either in terms of media and other technology used (e.g. audiovisual media and equipment and computers), or in terms of a systematic process which encompasses instructional design, development, delivery and evaluation.
  • intelligent backtracking — (algorithm)   An improved backtracking algorithm for Prolog interpreters, which records the point at which each logic variable becomes bound and, when a given set of bindings leads to failure, ignores any choice point which does not bind any of those variables. No choice from such a choice point can succeed since it does not change the bindings which caused the failure.
