Genetic Algorithms for a Large Scale Dynamic Allocation Problem

Mate-selection is the problem of deciding which animal should be culled and which should be mated in a breeding program. In addition, if the animal is to be mated, which animal from the other sex should it be mated with? With a linear objective function, integer linear programming was successfully used to solve the problem. When the relation between the animals' traits is additive, a strategy based on the classical index theory for selection with random allocation results in the optimal solution. Today, non-linear and non-additive objectives are introduced and the problem is becoming increasingly complex. In this paper, we formulate the problem as a multi-stage quadratic transportation model. We then solve the problem using two versions of Genetic Algorithms (GAs) on data collected from the Australian Dairy Industry. We then compare GAs against two conventional heurstic techniques; these are random search and simulated annealing. GAs are found to be better than the other heruistics for handling this large scale mate-selection problem.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
