It is shown that re-using results of previous computations can result in substantial reductions in computing time required. For instance, when the number of individuals increased by about 1% for matrices larger than 15,000, the time required for updating was less than 7% of that used for direct inversion from scratch. | Publication Type: | Journal Article | Source of Publication: | Journal of Animal Science, 91(6), p. 2583-2586 | Publisher: | American Society of Animal Science | Place of Publication: | United States of America | ISSN: | 1525-3163 0021-8812 |
