Evolutionary Computation Glossary

REORDERING:

(EC) A REORDERING operator is a REPRODUCTION OPERATOR which changes the order of GENEs in a CHROMOSOME, with the hope of bringing related genes closer together, thereby facilitating the production of BUILDING BLOCKs. cf INVERSION.

REPRODUCTION:

(biol, EC) The creation of a new INDIVIDUAL from two PARENTs (sexual REPRODUCTION). Asexual reproduction is the creation of a new individual from a single parent.

REPRODUCTION OPERATOR:

(EC) A mechanism which influences the way in which genetic information is passed on from PARENT(s) to OFFSPRING during REPRODUCTION. REPRODUCTION OPERATORs fall into three broad categories: CROSSOVER, MUTATION and REORDERING operators.

REQUISITE VARIETY:

In GENETIC ALGORITHMs, when the POPULATION fails to have a "requisite variety" CROSSOVER will no longer be a useful search operator because it will have a propensity to simply regenerate the PARENTs.

ROBOT:

"TheEncyclopedia Galactica defines a ROBOT as a mechanical apparatus designed to do the work of man. The marketing division of the Sirius Cybernetics Corporation defines a robot as `Your Plastic Pal Who's Fun To Be With'."

--- Douglas Adams (1979)
