Special Issue Information

Dear Colleagues,

Hybrid methods of machine learning/deep learning and metaheuristics represent a promising research field with the potential for significant contributions across various domains. According to the no free lunch (NFL) theorem, there is no universal approach capable of solving all challenges; therefore, each machine learning and deep learning model must be tailored to the specific problem at hand. This non-deterministic polynomial hard (NP-hard) challenge is known in the literature as the hyper-parameter tuning problem, and it has been shown that metaheuristics can prevent this problem with great success. This proposed Special Issue invites practical applications of hybrid methods combining machine learning/deep learning and metaheuristics. While hyper-parameter optimization is the primary focus, contributions addressing other challenges, such as feature selection, neural network (NN) weight initialization, deep networks training, etc., are also highly encouraged. Applications of tuned models, such as various types of recurrent neural networks (RNNs) for time-series prediction and classification, generative adversarial networks (GANs) for generating synthetic datasets, you only look once (YOLO) architectures for object detection, convolutional neural networks (CNNs) for image classification, and combined CNN/RNN models with traditional machine learning models (extreme gradient boosting—XGBoost, Adaptive Boosting—AdaBoost, support vector machines—SVM, etc.) are highly desirable topics for this Special Issue. Additionally, applications from various fields are welcome, including the prediction of energy prices, energy production from renewable sources, the load forecasting of virtual machine instances in the cloud, the classification of medical images and disease identification, combining audio–visual analysis in the form of Mel spectrograms for the detection of respiratory diseases and vehicle speed using CNN deep models, as well as many others.

Efficient sales route optimization is a critical challenge in logistics and distribution, especially under real-world conditions involving traffic variability and dynamic constraints. This study proposes a novel Hybrid Genetic Algorithm (GAAM-TS) that integrates Adaptive Mutation, Tabu Search, and an LSTM-based travel time prediction model to enable real-time, intelligent route planning. The approach addresses the limitations of traditional genetic algorithms by enhancing solution quality, maintaining population diversity, and incorporating data-driven traffic estimations via deep learning. Experimental results on real-world data from the NYC Taxi dataset show that GAAM-TS significantly outperforms both Standard GA and GA-AM variants, achieving up to 20% improvement in travel efficiency while maintaining robustness across problem sizes. Although GAAM-TS incurs higher computational costs, it is best suited for offline or batch optimization scenarios, whereas GA-AM provides a balanced alternative for near-real-time applications. The proposed methodology is applicable to last-mile delivery, fleet routing, and sales territory management, offering a scalable and adaptive solution. Future work will explore parallelization strategies and multi-objective extensions for sustainability-aware routing. Full article
