Artificial Immune Algorithm has the ability of doing a global searching quickly and stochastically.But it can't make use of enough system output information,and hence has to do a large redundancy repeat searching for the optimal solution,which reduces the efficiency of algorithm.Ant Colony Algorithm...
In the paper, a novel hybrid algorithm based on Baldwinian learning and PSO (BLPSO) is proposed to increase the diversity of the particles and to prevent premature convergence of PSO. Firstly, BLPSO adopts the Baldwinian operator to simulate the learning mechanism among the particles and employs...

To overcome the disadvantages of premature convergence and easy trapping into local optimum solutions, this paper proposes an improved particle swarm optimization algorithm (named NDWPSO algorithm) based on multiple hybrid strategies. Firstly, the elite
One of the most important problems in non-linear programming is to find out the global minimum of a given objective function. In this paper, a new hybrid algorithm which combines the random optimization method of Matyas (1965) and one of the well-known ordinary descent algorithms having an ef...
To rectify the indel errors, we first create a de Bruijn graph from the Illumina short reads. The indel errors of the long reads are then replaced with the widest path algorithm that maximizes the minimum k-mer coverage between two vertices in the de Bruijn graph. To correct the ...
a genetic operator which parallels to the select,crossover and mutation operators.The hybrid algorithm not only has a rather high convergence speed,but can locate the global optimum with a rather high probability.Two test functions are chosen to demonstrate the capability of the algorithm.The ...
