International Transactions in Operational Research, Volume 33, Issue 5, Page 3128-3157, September 2026.Abstract We propose the novel p‐branch‐and‐bound method for solving two‐stage stochastic programming problems whose deterministic equivalents are represented by non‐convex mixed‐integer quadratically constrained quadratic programming (MIQCQP) models. The precision of the solution generated by the p‐branch‐and‐bound method can be arbitrarily adjusted by

A multiplicative weights update algorithm for MINLP
EURO Journal on Computational Optimization, 2017 We discuss an application of the well-known multiplicative weights update (MWU) algorithm to non-convex and mixed-integer non-linear programming. We present applications to: (a) the distance geometry problem, which arises in the positioning of mobile ...

Graph‐based imitation and reinforcement learning for efficient Benders decomposition
AIChE Journal, Volume 72, Issue 6, June 2026.Abstract This work introduces an end‐to‐end graph‐based agent for accelerating the computational efficiency of Benders Decomposition. The agent's policy is parameterized by a graph neural network, which takes as input a bipartite graph representation of the master problem and proposes a candidate solution.
