In the present paper, we resolve the Set Covering Problem using the recently presented meta-heuristic named Binary Bat Algorithm. We use two variations of this algorithm. The Binary Bat Algorithm algorithm was created observing how the bats evade obstacles and find preys to eat, the use of echo-localization is how they do it. We made some changes using two different transfer and two discretization...
This paper proposed a new method of query-focused multi-documents summarization based on genetic algorithm, genetic algorithm is used to extract the sentences to form a summary, and it is based on a fitness function formed by three factors. Experimental result shows that the proposed summarization method can improve the performance of summary, genetic algorithm is efficient.
In order to solve nonlinear integer programming which is widely used in engineering fields, a particle swarm optimization based on genetic operators is put forward. The integer restriction of problems is transformed by coding solutions. According to optimal solutions of population and individual, the new particle is updated by crossover, mutation and selection operators. After the numerical experiment...
This paper proposed an interactive genetic algorithm (IGA) for football video scenes retrieval with multimodal features. Four audio-visual features (average shot duration, average motion activity average sound energy, and average speech rate) were extracted from each of the videos. Then they were encoded as chromosomes and indexed into search table. First, the proposed algorithm randomly selected...
