This paper studies the multi-constraint optimization problem under the background of time series data correlation, which is particularly important in the fields of finance, energy and meteorology. Aiming at the multiple constraints that need to be considered at the same time in practical applications, such as time, resources and risks, this paper proposes an optimization algorithm that combines time series correlation analysis. Through theoretical analysis and model design, the algorithm has been verified to be effective in multiple application scenarios, especially in improving financial forecasting and decision-making efficiency. Then, we use the financial market time series data into the algorithm of this paper for optimization experiments. The experimental results show that our new algorithm can not only improve the accuracy of similar financial market prediction models, but also significantly improve the decision-making efficiency. Finally, this paper looks forward to the improvement of the method in complex constraints and the direction of more efficient algorithm, which provides ideas for further research. © 2024 IEEE.

Nowadays, smart mobile devices (SMDs) support various computation-intensive and delay-sensitive applications, e.g., online games, and figure compression. However, SMDs have limited computing resources and battery energy and cannot execute all tasks of the above applications in a real-time manner. Cloud computing provides enormous computing resources and energy that can easily execute tasks offloaded from SMDs. However, could data centers (CDCs) are often located in remote sites, which leads to long transmission time. Small base stations (SBSs) offer high-bandwidth and low-latency services for SMDs, which solves the problem of cloud computing. However, it becomes a challenge to achieve the lowest cost in such a heterogeneous architecture including multiple SMDs, SBSs, and the CDC while meeting delay requirements of tasks. This work proposes a cost-minimized computation offloading strategy to minimize the total cost of the system. A constrained optimization problem is first formulated based on the hybrid architecture. Afterward, a two-stage optimization algorithm called a Lévy flights and Simulated Annealing-based Grey wolf optimizer (LSAG) is developed to optimize the total cost of the system. In the first stage, the optimal edge selection policy is determined given multiple available SBSs. In the second stage, task offloading and resource allocation among SMDs, SBSs, and the cloud are determined. Experiments with real-life tasks prove that LSAG significantly achieves lower cost with faster convergence speed than state-of-the-art peers. © 2023 IEEE.

- Nowadays, in the field of electromagnetic compatibility (EMC), numerical methods such as finite element analysis are often used for simulation analysis. These numerical methods take a long time to solve some complex simulation problems, which is not conducive to the optimal design of EMC. In particular, the intelligent optimization algorithm that needs continuous iterative calculation will not be realized because of the long optimization time. This paper realizes the innovative application of the uncertainty analysis method (Stochastic Collocation Method) in EMC optimization design. Two typical EMC optimization design problems, namely, the prediction of cable crosstalk and the design of shielding performance of metal boxes, are proposed to verify the effectiveness of the optimization algorithm. Meanwhile, its performance is compared with the classical intelligent optimization algorithms such as genetic algorithms and immune algorithms.

As the climate problem continues to worsen, carbon trading markets for energy conservation and emission reduction have been established in many countries. Accurate forecasting of carbon trading prices is not only a realistic problem, but also brings huge challenges to relevant researches. In this study, a novel predicting model is proposed to predict carbon price. And this model combines the advantages of the improved variational mode decomposition (IVMD) algorithm, multiscale entropy (MSE) algorithm, and the extreme learning machine (ELM) model improved by the intelligent optimization algorithm. Firstly, center frequency (CF) and mutual information (MI) entropy are utilized to jointly determine the number of decomposition layers of the variational mode decomposition (VMD), and avoid the problem of excessive decomposition. Subsequently, the complexity of each intrinsic mode function (IMF) from the improved variational mode decomposition is calculated by multiscale entropy, and intrinsic mode functions are recombined to reduce the complexity of subsequent modeling. At the last, the extreme learning machine optimized by the sparrow search algorithm (SSA) is adopted to model and predict the different sequence combinations. The performance indicators of the proposed model are significantly lower than others. For example, the root mean square error (RMSE) of the proposed model is 0.6653 in Hubei market, 0.9719 in Guangdong market and 1.2819 in Shanghai market. Additionally, the optimized extreme learning machine model is more suitable for the prediction of time series, which also provides an effective forecasting tool for related researchers.

This paper proposes an improved sparrow search algorithm (ADGSSA) based on multi-strategy fusion, and studies and verifies it in the thrust distribution of the dynamic positioning system of the new research vessel of Dalian Maritime University. First, the sparrow search algorithm is introduced. Aiming at its shortcomings in convergence speed, optimization accuracy and easy to fall into local optimality, a multi-strategy fusion improvement scheme including piecewise nonlinear dynamic random convergence factor strategy, warning position update condition and formula adjustment strategy, and golden sine perturbation strategy is proposed. Subsequently, the improved algorithm is applied to 12 benchmark functions with different characteristics and compared with Coati optimization algorithm (COA), whale optimization algorithm (WOA) and sparrow search algorithm (SSA). Experimental results show that ADGSSA outperforms the other three algorithms in optimization accuracy, convergence performance and stability. In the evaluation of 12 benchmark functions, ADGSSA demonstrates superior performance compared to SSA, WOA, and COA. Specifically, ADGSSA achieves the closest optimal value in 83% of the functions, provides the best average value in 85% of the functions, and has the lowest standard deviation in 75% of the functions. In the actual application of the thrust distribution system, ADGSSA shows significant advantages. Compared with WOA, the average power of the thruster is reduced by about 75%;compared with SSA, it is reduced by about 35%;compared with COA, it is reduced by about 17%. In addition, in 12 sets of thrust tests, the thruster wear of ADGSSA reached the smallest proportion of 82% among the four algorithms, which is significantly better than other algorithms. The test results and convergence curves further show that ADGSSA has significant effectiveness and superiority in improving the thrust distribution performance of the dynamic positioning system, proving the poten

Designing reduced congestion road networks via an elitist adaptive chemical reaction optimization

引用

We propose a new approach for solving a variant of the transportation Network Design Problem (NDP) where network congestion is reduced via traffic pattern redesign. The investigated NDP selects a set of roads to be converted from two-way traffic to one-way traffic. This allows increased traffic flow in the selected roads at the cost of restricting flow in the opposing direction roads. An optimal set of converted roads can result in significant congestion reduction for the network without the high construction costs associated with network capacity expansion. The new approach builds on the recently developed Chemical Reaction optimization (CRO) metaheuristic and leverages Markov chain traffic assignment to predict traffic flow changes in response to network modifications. We propose an elitist and adaptive version of the CRO metaheuristic allowing it to more efficiently search for optimal solutions. We deploy the proposed approach to the cities of Abu Dhabi and Sioux Falls and report on our results. We also compare the Elitist Adaptive CRO (EACRO) results to those of Genetic Algorithm (GA) to demonstrate its performance. Compared to GA, the proposed approach reduces network congestions faster using fewer objective function evaluations. It also produces lower network congestion designs using long optimization runs. However, we find the algorithm to be sensitive to parameter calibration and dependent on the use of elitism for good performance. We explore the internal dynamics of the proposed algorithm and investigate its search effectiveness to understand its superior performance when compared to GA.

Location information of individual nodes is important in the implementation of necessary network functions. While extensive studies focus on localization techniques in 2D space, few approaches have been proposed for 3D positioning, which brings the location closer to the reality with more complex calculation consumptions for high accuracy. In this paper, an effective range-free localization scheme is proposed for 3D space localization, and the sensitivity of parameters is evaluated. Firstly, we present an improved algorithm (MDV-Hop), that the average distance per hop of the anchor nodes is calculated by root-mean-square error (RMSE), and is dynamically corrected in groups with the weighted RMSE based on group hops. For more improvement in accuracy, we expand particle swarm optimization (PSO) of intelligent optimization algorithms to MDV-Hop localization algorithm, called PMDV-hop, in which the parameters (inertia weight and trust coefficient) in PSO are calculated dynamically. Secondly, the effect of various localization parameters affecting the PMDV-hop performance is also present. The simulation results show that PMDV-hop performs better in positioning accuracy with limited energy.

INTERNATIONAL TRANSACTIONS ON ELECTRICAL ENERGY SYSTEMS 2017年第7期27卷 n/a-N.PAG页

Phasor measurement unit (PMU) is one of the state estimation devices that can synchronously measure both the voltage and the current phasor. Different methods have been presented for detecting the optimal number of PMUs. Some disadvantages of these methods are high computation burden, dependence on tuning parameters, complex calculation, and lack of accountability in large-scale power networks. This paper presents the novel strategy called rational random walk (RRW) to tackle these disadvantages. The first advantage of the proposed approach is the simple structure than conventional approaches. The second advantage is the independence of tuning parameters. The third advantage is the capability of implementation on the large-scale power networks. The fourth advantage is the use of 2-stage strategy for reducing the search space. The fifth advantage is capability of RRW to superimpose on the conventional optimization algorithm to enhance the convergence speed. The sixth advantage is capability of RRW to extract the optimal PMU placement under N-1 contingency. Superiority of the RRW in comparison with other methods is verified by implementing on the standard Institute of Electrical and Electronics Engineers (IEEE) test systems. Moreover, the proposed method has been used to specify and test the minimum number of PMUs in 2 real life systems in Iran power network. One of them is 400kV, and the other one is 230kV, and also a large-scale test system polish 2383-bus power system.

The Teaching-Learning-Based optimization (TLBO) algorithm is being extended to a broader range of applied optimization problems in the literature, mimicking the teaching-learning process. This paper proposes an Advanced Teaching-Learning-Based optimization (Ad-TLBO) algorithm to enhance the efficiency and performance of the original version of TLBO in terms of accuracy, convergence rate, and reliability characteristics. The advancement is obtained by modifying the initialization, search approach, and structure of the two main phases of this algorithm in four steps to improve exploration and exploitation capability. Efficiency comparisons are shown in four challenges with various benchmark functions with multimodal, separable, differentiable, and continuity characteristics. The results are compared with several intelligent optimization algorithms. It is also deduced that this algorithm outperforms all investigated optimization algorithms in terms of accuracy, convergence speed, and success to reach acceptable solutions for various benchmark functions.
