As part of IOS 2026, presenters may choose to submit papers to the refereed proceedings—this marks the second edition of such proceedings in the IOS conference series.
The purpose of the refereed proceedings is to provide members of the optimization community a new outlet for having their work highlighted and reviewed. Submissions were refereed by the program committee and external reviewers. Of the many strong papers submitted, the following papers were accepted to the 2026 IOS Refereed Proceedings:
Zahra Khatti, Daniel Robinson, Frank Edward Curtis, “Fair Supervised Learning Through Constraints on Smooth Nonconvex Unfairness-Measure Surrogates”

Thank you to everyone who submitted, and to all of the referees for their efforts.
Submission Details
We welcome papers from all aspects of mathematical optimization. Submitted papers should fall within the scope of mathematical optimization in a broad sense, including new algorithmic and structural results as well as computational studies and applications. Papers from all areas of optimization are encouraged, including (but not limited to) continuous, discrete, stochastic, and applied optimization.
All papers accepted to the refereed proceedings will be highlighted on the IOS website. Furthermore, accepted papers that are also journal-ready (in terms of quality and completeness) will be given the opportunity to submit their work to the INFORMS Journal on Optimization (IJOO) for an expedited review process.
Submitted papers cannot be in submission to any other refereed venue. Similarly, for a submitted paper to be considered for IJOO, it cannot be submitted to any other refereed venue. Any other journal rules must also be followed for journal consideration.
IMPORTANT: Before submitting a refereed paper, authors are required to submit an abstract [associated to the submitted refereed paper] through the general submission system—either as part of an invited session or as a contributed submission. Please note that the notification date for refereed papers falls after the speaker registration deadline. Therefore, once an abstract has been accepted, at least one author must commit to registering and presenting the work at the conference regardless of the outcome of the refereed paper review.
A weblink will be created to the list of all accepted papers. Furthermore, all accepted papers will be publicly announced.
How to submit:
Please submit your paper on OpenReview. Please note that if a non-institutional email is used to create a new profile on OpenReview, then it may take up to two weeks for the profile to be approved. New accounts created using institutional emails should be activated automatically.
Submission Format:
Paper submissions should be in the form of an extended abstract, using the INFORMS Journal on Optimization (IJOO) template. Please follow the IJOO Submission Guidelines. In particular, the manuscripts should follow the format specifications for font size and spacing. Furthermore, submissions should be anonymized (declare the document class as \documentclass[ijoo,blindrev]{informs4} ). Any papers that include author identification (whether on the title page or elsewhere) will be returned to the authors. The page limit for paper submissions is 14 pages plus references. Any details that are missing from these 14 pages should be placed into an appendix. However, note that only the first 14 pages will be reviewed at IOS. If appendices are needed, then please be mindful that any paper offered expedited-review at IJOO will be subject to the journal’s rules.
If any questions arise, please email Joseph Paat (joseph.paat@ubc.ca) or Aleksandr Kazachkov (akazachkov@ufl.edu).
