Operator and parameter adaptation in genetic algorithms [PDF]

Soft Computing, 1997
Genetic Algorithms are a class of powerful, robust search techniques based on genetic inheritance and the Darwinian metaphor of “Natural Selection”. These algorithms maintain a finite memory of individual points on the search landscape known as the “population”.

Genetic evaluation of fertility using direct and correlated traits [PDF]

, 2003
Poor fertility has become a major reason for involuntary culling of dairy cows in the United Kingdom. Calving interval (CI) and body condition score (BCS) are recorded, heritable, genetically correlated with each other, and could be used to extend the ...
