In past few years, Web-based application and services are growing rapidly and this growing demands needs different Quality of Services (QoS) requirements for efficient use of such web-based services. The purpose behind utilizing these application resources could be tarnished if the fundamental communication network does not fulfill the QoS requirements. However, different applications have distinct QoS necessities as each application have different priorities. The main concern is to come across such solution which will optimize the network not in the terms of minimum number of hops but in terms of Qos parameters of network, relies upon application running over that network. This issue comes under multi-objective optimization problem (MOOP) and Genetic Algorithm (GA) is one of the techniques which can possibly control numerous parameters all together, and hence GA is applied to solve MOOP, which can enhance the QoS. This paper surveys the various MOOP techniques and then gives the best solution among them.

To improve the convergence and distribution of a multi-objective optimization algorithm, a hybrid multi-objective optimization algorithm, based on the quantum particle swarm optimization (QPSO) algorithm and adaptive ranks clone and neighbor list-based immune algorithm (NNIA2), is proposed. The contribution of this work is threefold. First, the vicinity distance was used instead of the crowding distance to update the archived optimal solutions in the QPSO algorithm. The archived optimal solutions are updated and maintained by using the dynamic vicinity distance based m-nearest neighbor list in the QPSO algorithm. Secondly, an adaptive dynamic threshold of unfitness function for constraint handling is introduced in the process. It is related to the evolution algebra and the feasible solution. Thirdly, a new metric called the distribution metric is proposed to depict the diversity and distribution of the Pareto optimal. In order to verify the validity and feasibility of the QPSO-NNIA2 algorithm, we compare it with the QPSO, NNIA2, NSGA-II, MOEA/D, and SPEA2 algorithms in solving unconstrained and constrained multi-objective problems. The simulation results show that the QPSO-NNIA2 algorithm achieves superior convergence and superior performance by three metrics compared to other algorithms.

multi-objective optimization problem (MOP) plays an increasingly important role in finance and engineering. In order to obtain more accurate and evenly distributed target solution set to a multi-objective programming, a novel swarm exploring neural dynamics (SEND) method is proposed, analyzed and applied in this paper. Specifically, a scalarization approach is firstly applied to transform the MOP into a group of subproblems. Secondly, each subproblem is solved by a varying parameter recurrent neural network (VP-RNN). By solving these problems, a group of Pareto optimal solutions are obtained. Thirdly, a population evolution weight optimization algorithm is used to diversify the solution set to obtain evenly distributed solutions. Simulation results demonstrate that the proposed SEND method can obtain a more accurate and evenly distributed solution set than some previous methods and the convergence rate is faster than the state-of-art methods, such as collaborative neurodynamic approach (CNA).

This paper studies the multi-objective optimization problems (MOPs) of Markovian jump systems (MJSs) closed by general controllers. Firstly, the linear quadratic regulator (LQR) problem of MJSs closed by a general controller with sampled or synchronous modes is studied and estimated by a mode-separation approach, whose traditional algebraic Riccati equations (AREs) are removed. Meanwhile, two traditional situations about mode-dependent and -independent controllers are contained as special ones. Secondly, an MOP deeply depending on mode separations is proposed and solved by the non-dominated sorting whale optimization algorithm (NSWOA) such that the minimum value of LQR problem and the maximum expectation value of summed mode dwell times in the same mode separation are simultaneously optimized. Particularly, in order to further improve the estimation effect, a single-objective optimization problem (SOP) is presented and computed by applying the deep deterministic policy gradient (DDPG) technique, whose optimal controller in addition to its best mode separation is given in detail. Thirdly, similarly but more generally, another controller with its mode and state both sampled is constructed to realize the LQR problem, whose effects are better than some existing methods and can also be improved by solving some optimization problems. Finally, a simulation is used to verify the effectiveness and superiority of the proposed methods. Note to Practitioners-This paper addresses the LQR problem for MJSs, commonly used in automation and control with uncertainty and frequent mode switching. Traditional LQR methods rely on mode-dependent controllers and AREs, leading to high computational costs and real-time demands, especially in industrial settings. To overcome these challenges, this paper proposes a general controller design and an MOP, replacing AREs with a mode-separation strategy, simplifying the process and reducing costs. A controller with both mode and state sampling is a

In this paper, a modified Competitive Mechanism multi-objective Particle Swarm optimization (MCMOPSO) algorithm is presented for multi-objective optimization. The algorithm consists of an improved leader selection scheme called multi-competition leader selection. Under this scheme, particles move to the winner among the elite particles for the social cognitive by comparing the nearest angle or the farthest angle of several randomly selected elite particles. Besides, as the inertia weight plays an important role in controlling the previous velocity of each particle, the competitive mechanism is applied to the inertia weight in order to investigate for the most suitable balance between the exploration and exploitation abilities of the algorithm during the search process. The experimental results show that the proposed algorithm outperforms four other popular multi-objective particle swarm optimization algorithms most of the time on thirty-seven benchmarks in terms of inverted generational distance. Furthermore, the proposed algorithm is applied to the signalized traffic problem to optimize the effective green time of each phase, and the proposed algorithm performs better than other MOPSO algorithms for the traffic problem in terms of hypervolume.

In optimization and decision-making, multi-objective optimization has emerged as a pivotal challenge. Over the past three decades, the concerted efforts of scholars and practitioners across various disciplines have significantly advanced the study and implementation of multi-objective Evolutionary Algorithms (MOEAs). MOEAs stand at the forefront of multi-objective decision-making methodologies, marking a vibrant area of inquiry within evolutionary computation. This body of work categorizes MOEAs into three distinct streams: Decomposition-based MOEA algorithms, Dominant relationship-based MOEA algorithms, and Evaluation index-based MOEA algorithms. Focusing specifically on dominance-based MOEAs, this study integrates them with chaotic evolution (CE) strategies to enhance the efficacy of multi-objective optimization processes. Through comparative analysis against traditional algorithms, the newly proposed chaotic MOEA demonstrates superior optimization performance, thereby setting a robust groundwork for the continuous evolution and application of MOEAs.

The coupling of renewable energy sources with electrolyzers under stand-alone conditions significantly enhances the operational efficiency and improves the cost-effectiveness of electrolyzers as a technologically viable and sustainable solution for green hydrogen production. To address the configuration optimization challenge in hybrid electrolyzer systems integrating alkaline water electrolysis (AWE) and proton exchange membrane electrolysis (PEME), this study proposes an innovative methodology leveraging the morphological analysis of Pareto frontiers to determine the optimal solutions under multi-objective functions including the hydrogen production cost and efficiency. Then, the complementary advantages of AWE and PEME are explored. The proposed methodology demonstrated significant performance improvements compared with the single-objective optimization function. When contrasted with the economic optimization function, the hybrid system achieved a 1.00% reduction in hydrogen production costs while enhancing the utilization efficiency by 21.71%. Conversely, relative to the efficiency-focused optimization function, the proposed method maintained a marginal 5.22% reduction in utilization efficiency while achieving a 6.46% improvement in economic performance. These comparative results empirically validate that the proposed hybrid electrolyzer configuration, through the implementation of the novel optimization framework, successfully establishes an optimal balance between the economy and efficiency of hydrogen production. Additionally, a discussion on the key factors affecting the rated power and mixing ratio of the hybrid electrolyzer in this research topic is provided.

multi-objective test case prioritization (MOTCP) problems are a critical task in software testing. It aims to prioritize test cases with multiple test standards and targets. However, there are few studies focusing on resolving MOTCP problems and the performance of existing methods is not promising. In this paper, we propose anew algorithm named PMOEA/D-VW which is based on the original MOEA/D (multi-objective evolutionary algorithms based on decomposition) framework. We improve MOEA/D by making improvements in the crossover operator, the weight vector generation and updating strategy, and the neighborhood changing strategy. We conduct extensive experiments on six open source Java projects to validate the effectiveness of PMOEA/D-VW. Experimental results show that: (1) PMOEA/D-VW achieves 98.67% in terms of APFDc (the average of the percentage of faults detected) on average and improves the state-of-the-art (SOTA) MOPSO by 6.77%. (2) The Pareto optimal (PS) solutions achieved by PMOEA/D-VW have better distribution than those of the baseline methods. (3) The new crossover operator IPBX can contribute to improve the performance of PMOEA/D-VW.

With the development of unmanned aerial vehicle (UAV) technology, using UAVs as aerial communication platforms to provide additional communication services is a promising technology. However, due to the scarcity of spectrum resources, UAV will inevitably causes unintentional interference to primary users (PUs) when transmitting data to secondary users (SUs). Aiming at this problem, with the help of the multi-objective optimization problem (MOOP) framework, this paper studies the trade-off between UAV's communication rate and UAV's unintentional interference by optimizing UAV's trajectory, UAV's transmission power, and SU's scheduling. Specifically, we consider a cognitive UAV communication scenario that a single UAV needs to transmit data to multiple SUs in a shared spectrum scenario. During this process, if the existing PUs receive unintentional interference from the UAV does not exceed a given threshold which is also called interference temperature (IT), it will be regarded as a normal communication state. Then, a MOOP is established that includes maximizing the minimum UAV-SU communication rate and maximizing the times that PUs are in normal communication states. Finally, with the help of $\epsilon -constraint$ method and stochastic submodular optimization algorithm, we propose an iterative algorithm to obtain the approximate Pareto front. The tradeoff between UAV's communication rate and UAV's unintentional interference is analyzed through numerical simulation.
