The Mathematical Optimization Society has awarded the Beale — Orchard-Hays Prize to ORFE Professor Stellato and his co-authors for their work in creating the OSQP: An Operator Splitting Solver for Quadratic Programs. The Beale — Orchard-Hays Prize, awarded every three years by the Mathematical Optimization Society, recognizes a paper or book that exemplifies "excellence in computational mathematical programming." Named in honor of pioneers Martin Beale and William Orchard-Hays, it celebrates outstanding contributions to computational mathematical optimization.
This award, which was presented at the International Symposium on Mathematical Programming, commends the following aspects of this work: the robust implementation of the software, with attention to issues such as preprocessing problem instance and detecting infeasibility; the long list of users and successful practical applications of the software; the impact the paper has already made on the field, as evidenced by its large number of citations; the careful and extensive numerical testing in the paper.
