As\nimplemented in the package, the ant colony algorithm randomly\nselects items to build a model of a specified length, then\nupdates the probability of item selection according to the fit\nof the best model within each set of searches. The algorithm\ncontinues until the same items are selected by multiple ants a\ngiven number of times in a row. On the other hand, the Tabu\nsearch changes one parameter at a time to be either free,\nconstrained, or fixed while keeping track of the changes made\nand putting changes that result in worse fit in a \"tabu\" list\nso that the algorithm does not revisit them for some number of\nsearches.
