ModRef 2024

The 23rd workshop on Constraint Modelling and Reformulation

September 2nd, 2024; Part of CP 2024

ModRef 2024 is the 23rd in a series of workshops on Constraint Modelling and Reformulation organized as part of CP 2024, the 30st International Conference on Principles and Practice of Constraint Programming. It will be held on September 2nd, directly preceding the CP conference.

The importance of modelling and model reformulation is widely recognised, particularly for CP but also for MIP, SAT, SMT and other kinds of general-purpose solvers. There has been significant research effort in recent years into modelling and model reformulation, such as automating techniques used by expert modellers, and developing tools and techniques to target multiple types of solvers from one model.

The purpose of ModRef is to be a forum for all kinds of work in constraint modelling, including new models or new modelling ideas for any amenable problem (whether a new application or a classic benchmark), constraint reformulation techniques to improve the performance of models when solved by general-purpose solvers, and automated modelling techniques, tools, and languages. We solicit original papers that contribute to the understanding of constraint modelling or model reformulation.

Workshop topics include:

Important Dates

Camera ready version August 23rd, 2024
Workshop day September 2nd, 2024

Call for Papers

This year ModRef will again accept paper submissions. In addition to the presentation of research results, we especially welcome submissions of novel (ongoing) work, recent breakthroughs, future directions, and descriptions of interesting aspects of existing systems.

There are three types of paper submissions: extended abstracts (at most two pages), short papers (at most eight pages) and long papers (at most fifteen pages). References are not part of the page limit. Papers are submitted through EasyChair, as a PDF file following LIPIcs guidelines. There is no requirement for papers to be anonymised before submission.

We also accept (and encourage) non-traditional electronic submissions, such as interactive works/tool demonstrations. In this case, please contact the chairs to discuss the suitability of your submission for ModRef.

All submissions will be reviewed and those that are well-written and make a worthwhile contribution to the topic of the workshop will be accepted for publication in the workshop proceedings. The proceedings will be available electronically at CP 2024. Accepted contributions will be allowed a time slot for a presentation at the workshop. In-person presentation is preferable, but we will allow remote presentation of papers when necessary.
