Discrete multi-objective optimization of particle swarm optimizer algorithm for multi-agents collaborative planning by Xiao-bo SHI, Yin ZHANG, Shan ZHAO, Deng-ming XIAO

“…Although multiple mobile agents(MA)collaboration can quickly and efficiently complete data aggregation in wireless sensor network,the MA carrying data packages extensively increase along with a raise in the number of data source nodes accessed by MA,which causes unbalanced energy load of sensor nodes,high energy consumption of partial source nodes,and shortened lifetime of networks.The existing related works mainly focus on the objective of decreasing total energy consumption of multiple MA,without considering that rapidly energy consumption of partial source nodes has a negative effect on networks lifetime.Therefore,discrete multi-objective optimization of particle swarm algorithm was proposed,which used the total network energy consumption and mobile agent load balancing as fitness function for the approximate optimal itinerary plan in multiple mobile agent collaboration.Furthermore,the simulation result of the proposed algorithm is better than the similar algorithm in total energy consumption and network lifetime.…”

Multi-objective Optimization Design of Sleeve Roller Chain Transmission based on Differential Evolution Algorithm by Liu Wei, Lu Qingbo

“…The optimum design of sleeve roller chain transmission is most researched by the single objective optimization.A multi-objective optimization model of this problem is established by maximum single row chain transmission efficiency and maximum fatigue life.A modified constrained handling strategy and rounding strategy are incorporated into the multi-objective differential evolution algorithm based on gauss mutation and a multi-objective mixed-discrete variables differential evolution algorithm is proposed.The engineering example shows that the optimum results meet the design requirements and the new algorithm is effective and has certain value for other engineering problem.…”

Energy-efficient optimal algorithm based on uplink multi-user very large MIMO system by UYing H, IBao-feng J, UANGYong-ming H, UFei Y, ANGLV-xi Y

“…Using the energy efficiency lower bound as the optimization criterion,a resource allocation algorithm was investigated under uplink multi-user very large MIMO systems.Specifically,both the number of antenna arrays at the BS and the transmit data rate at the user are adjusted to maximize the energy efficiency,in which the power consumption accounts for both transmit power and circuit power,meanwhile the BS uses a zero forcing(ZF) receiver.The existence of a unique globally optimal resource allocation solution was demonstrated by exploiting the properties of objective function.Furthermore,by transforming the originally fractional optimization problem into an equivalent subtractive form using the properties of fractional programming,an iterative resource allocation algorithm was developed to achieve the optimum was developed.Simulation results show that the algorithm converge to a near optimal solution only with a small number of iterations.…”
