The Workshop on Big Optimization (WBO25) aims to bring together researchers, practitioners, and industry experts to explore the challenges and advancements in solving large-scale, complex optimization problems. The workshop focuses on fostering collaboration across disciplines such as computer science, operations research, artificial intelligence, and applied mathematics.

The workshop particularly emphasizes innovative approaches in heuristics, metaheuristics, and hybrid methods, as well as their applications in big data optimization, high-dimensional problem spaces, and computationally expensive domains. Participants will have the opportunity to discuss emerging trends, share best practices, and identify future directions for research in this rapidly evolving field.

WBO25 is an inclusive platform, welcoming contributions that span theoretical foundations, algorithmic developments, real-world applications, and computational frameworks. The workshop will be held in a hybrid format, allowing participants to join both in person and online.

Accepted regular and short papers will be published as post-proceedings in the Studies in Big Data (SBD) series by Springer.

The focus of WBO25 is on the challenges and opportunities that arise in solving large-scale and highly complex optimization problems. The workshop will feature plenary talks, technical sessions, and networking opportunities to foster collaboration and innovation within the scientific and industrial communities.

Topics of Interest: heuristics and metaheuristics, large-scale optimization, AI in optimization, scalable methodologies and frameworks, and various applications in sectors such as energy, logistics, healthcare, network design, and supply chain.

Submission Guidelines

We invite three types of contributions:

• Regular Papers (maximum 15 pages): novel and original research contributions.
• Short Papers (extended abstract of up to 10 pages): novel research works in progress or with preliminary results.
• Oral Presentations: high-quality published or preliminary recent works. These contributions are considered for presentation only and are not included in the proceedings.

All submissions must be prepared using the Springer Conference proceedings template. (available here).

Accepted regular and short papers will be published as post-proceedings in the Studies in Big Data (SBD) series by Springer. Accepted abstract contributions (oral presentations) will be considered for presentation at the workshop based on the number of submissions and available slots, and will not be included in the proceedings volume. Instead, an electronic book containing these abstracts will be made available on the workshop website.

At least one author of each accepted paper (regular or short) is required to register and present the work at WBO25 for the paper to appear in the post-proceedings. Each participant can present at most one paper.

Special Issues

Selected high-quality papers from the workshop will be invited for submission to one or more post-conference Special Issues in international journals (to be announced soon). Significantly extended and revised versions of these selected papers will be reviewed for inclusion. The selection will be based on originality, technical quality, and relevance to the workshop topics.
