Khachiyan Prize

The Khachiyan Prize of the INFORMS Optimization Society was established in 2010 and is awarded annually at the fall INFORMS Annual Meeting to an individual or a team for life-time achievements in the area of optimization. The award recognizes a sustained career of scholarship from nominees who are still active at the year of the nomination. The prize serves as an esteemed recognition of innovativeness and impact in the area of optimization, including theory and applications. Recipients of the INFORMS John von Neumann Theory Prize or the MPS/SIAM Dantzig Prize in prior years are not eligible for the Khachiyan Prize.

The award includes a cash amount of $1,000 and a citation certificate. The award winner(s) will be invited to give a thirty minute presentation at the INFORMS National Meeting. The winners will be responsible for all travel expenses associated with the presentation of their paper at the INFORMS meeting. Award winners are also asked to contribute an article about their award-winning work to the Optimization Society newsletter.

Leonid Khachiyan

Using the ellipsoid algorithm, in 1979, Leonid Khachiyan was the first to prove that linear optimization can be solved in polynomial time. Read more about Leonid Khachiyan and the importance of his work in optimization.

  1. The Khachiyan Prize is awarded for outstanding life-time contributions to the field of optimization by an individual or team.
  2. The topic of the contribution must belong to the field of optimization in its broadest sense.
  3. Recipients of the INFORMS John von Neumann Theory Prize or the MPS/SIAM Dantzig Prize in prior years are not eligible for the Khachiyan Prize.
