... In iteration i, we compute the sums of all subsets of {x1 , x2 , ..., xi }, using as a starting point the sums of all subsets of {x1 , x2 , ..., xi−1 }. Once we find the sum of a subset S’ is greater than t, we ignore that sum, as there is no reason to maintain it. No superset of S’ can possibly be ...

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.
