... In particular, we consider the following counter-example: A = [≥n/2∅ + 1, . . . , n, 1, 2, 3, . . . , ≥n/2∅] . Lemma 1 A is not 90% sorted. Proof. Assume, by contradiction, that the list is 90% sorted. Then, there must be some 90% of the elements that are correctly ordered with respect to each other ...

Genetic algorithm
In the field of artificial intelligence, a genetic algorithm (GA) is a search heuristic that mimics the process of natural selection. This heuristic (also sometimes called a metaheuristic) is routinely used to generate useful solutions to optimization and search problems. Genetic algorithms belong to the larger class of evolutionary algorithms (EA), which generate solutions to optimization problems using techniques inspired by natural evolution, such as inheritance, mutation, selection, and crossover.
