Harrington Park, NJ — December 26, 2025 — We successfully solved the MIPLIB 2017 benchmark instance minutedispatchstrategy, achieving an objective value of 3,109.903 and closing the solver-reported optimality gap to 0.00%using ODH|Xpress.

The instance minutedispatchstrategy is described in MIPLIB as a dispatch strategy for a small micro-grid and is a large-scale mixed-binary optimization model with 41,761 variables and 80,194 constraints.

“This result demonstrates our ability to push challenging benchmark models to a certified solve, combining strong heuristics with rigorous MIP optimization,” said Robert Ashford, CEO.
