Terms and Definitions
Crossover..In genetic algorithm, it is the process of combining features of a chromosome
with other chromosome(s).
Evolutionary.algorithm. An algorithm incorporating aspects of natural selection
or survival of the fittest.
Fitness.function. In genetic algorithm, it is a measure of how well a chromosome
can perform in certain environments (functions).
Genetic algorithm. An evolutionary algorithm which generates each individual
from some encoded form known as ???chromosomes??? or ???genome.???
Mutation. In genetic algorithm, it is defined as a change in form or qualities of
chromosomes.
Ontology. Ontology looks for semantic and ontological primitives and concepts to
describe aspects or parts of ???the world.???
Restructuring. Restructuring is replacing query terms using synonyms so that
