- memetic algorithm — (algorithm) A genetic algorithm or evolutionary algorithm which includes a non-genetic local search to improve genotypes. The term comes from the Richard Dawkin's term "meme". One big difference between memes and genes is that memes are processed and possibly improved by the people that hold them - something that cannot happen to genes. It is this advantage that the memetic algorithm has over simple genetic or evolutionary algorithms. These algorithms are useful in solving complex problems, such as the "Travelling Salesman Problem," which involves finding the shortest path through a large number of nodes, or in creating artificial life to test evolutionary theories. Memetic algorithms are one kind of metaheuristic. (07 July 1997)

- method invocation — (programming) In object-oriented programming, the way the program looks up the right code to run when a method with a given name is called ("invoked") on an object. The method is first looked for in the object's class, then that class's superclass and so on up the class hierarchy until a method with the given name is found (the name is "resolved"). Generally, method lookup cannot be performed at compile time because the object's class is not known until run time. This is the case for an object method whereas a class method is just an ordinary function (that is bundled with a given class) and can be resolved at compile time (or load time in the case of a dynamically loaded library).
