Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your research to be considered for the Special Issue “Emerging Research in Optimization and Machine Learning”. This Special Issue aims to present research developments on the dynamic interplay between these two pivotal fields. In an era where artificial intelligence and computational methods are revolutionizing industries and scientific disciplines, understanding how optimization techniques enhance machine learning algorithms—and vice versa—is of paramount importance.

This Special Issue aims to showcase the latest advancements across a spectrum of topics, including mathematical programming, nonsmooth optimization, constrained optimization, optimization in deep learning, convex and nonconvex optimization, metaheuristics, multi-objective optimization, methods for regularized models, stochastic optimization, optimization in reinforcement learning, support vector machines, and clustering. We also invite contributions on applications of these topics to model systems in physics, chemistry, biology, and engineering.

We invite researchers to submit original research articles, reviews, and perspectives that explore the symbiosis between optimization and machine learning. Whether you are developing novel optimization methodologies tailored for machine learning tasks, integrating optimization principles into machine learning frameworks, or unveiling applications that harness the power of this symbiotic relationship, we welcome your contributions.

Through this Special Issue, we seek to foster collaboration, inspire innovation, and advance the collective understanding of optimization and machine learning.

Topics of interest include (but are not limited to) the following:

  • Mathematical programming;
  • Nonsmooth optimization;
  • Constrained optimization;
  • Optimization in deep learning;
  • Convex and nonconvex optimization;
  • Metaheuristics;
  • Multi-objective optimization;
  • Methods for regularized models;
  • Stochastic optimization;
  • Optimization in reinforcement learning;
  • Support vector machines;
  • Clustering.

This work develops a scheduling tool for electric buses that accounts for daily disruptions while minimizing the operational costs. The contribution of this study lies in the development of electric bus schedules that consider many factors, such as multiple depots, multiple charging stations, and stochastic travel times, providing schedules resilient to extreme conditions. The developed model is a mixed-integer linear program (MILP) with chance constraints. The main decision variables are the assignment of electric vehicles to scheduled trips and charging events to ensure the improved operation of daily services under uncertain conditions. Numerical experiments and a sensitivity analysis based on the variation in travel times are conducted, demonstrating the performance of our solution approach. The results from these experiments indicate that the variant of the model with the chance constraint produces schedules with lower operational costs compared to the case where the chance constraints are not introduced.
