It was an honor and a pleasure to chair the 2025 Mixed Integer Programming Workshop from June 2 to 6 in Minneapolis, MN. For everyone that missed it, we missed you too but you may catch up on the talk/poster details and competition winners via mixedinteger.org/2025 and the #mip2025 workshop program.

Christina Büsing talked at the #mip2025 workshop about robust binary linear optimization under budget uncertainty.
There is a result that reframes this problem as a mixed-integer linear program. However, for a problem as simple as a knapsack with 50 items, CPLEX could not solve it in one hour.

Martine Labbé talks at the #mip2025 workshop about new cutting planes for chance-constrained stochastic problems.
One thing I didn’t known is that chance-constrained linear problems have a feasible set consisting of a possibility nonconvex set based on the union of exponential polyhedra.
