Improved ant colony algorithm based on natural selection strategy for solving TSP problem by Hua-feng WU, Xin-qiang CHEN, Qi-huang MAO, Qian-nan ZHANG, Shou-chun ZHANG

“…To solve basic ant colony algorithm's drawbacks of low convergence rate,easiness of trapping in local optimal solution,an improved ant colony algorithm based on natural selection was proposed.The improved algorithm employed evolution strategy of survival the fittest in natural lection to enhance pheromones in paths whose random evolution factor was bigger than threshold of evolution drift factor in each process of iteration.It could accelerate convergence rate effectively.Besides the introduction of random evolution factor reduced probability of trapping local optimal solution notably.The proposed algorithm was applied to classic TSP problem to find better solution for TSP.Simulation results depict the improved algorithm has better optimal solution and higher convergence rate.…”

Routing selection algorithm based on ant colony optimization in mobile P2P network by Lifang MA, Weifeng CHEN, Shizhan LAN, Song LU, Yulan ZHANG, Xiaobin MO, Changzhi HE

“…For the dynamic of P2P network and the limited energy of the mobile node,enhancing the mobile P2P data transmission efficiency is essential.By using ant colony optimization algorithm the ant pheromones were combined with the node energy and communication bandwidth.When ACO selected the path,the concentration of the pheromone on its optimization path was reduced.The routing selection strategy was adaptively adjusted by the pheromone density of routing probability table in order to avoid network congestion and excessive energy consumption of individual nodes.A multipath routing selection algorithm in mobile P2P network was proposed.Experiment results show that the proposed algorithm can reduce packet loss rate and the average delay compared with EDSR routing protocol,prolonging the lifecycle of the whole network.…”
