Following the 2020 and 2021 successes, the OR/MS Tomorrow mini poster competition came back in Fall 2023. In total, nineteen high-quality submissions competed with one another in the undergraduate, master’s, and Ph.D. categories. Thank you all for your excellent work and for submitting it to our competition. Candidates were required to design one letter-sized page to communicate their research topic to the broader audience in the OR/MS community. A group of judges chose the winners based on the novelty of the topic, maturity of the content, quality of the information, engagement, and aesthetics.
