By: J. Zhang* & O. Ozaltn

author keywords: bilevel programming; stochastic programming; integer programming; value function; branch and bound
TL;DR: An exact value function-based approach to solve a class of bilevel integer programs with stochastic right-hand sides is developed and the integer complementary slackness theorem is generalized to bileVEL integer programs. (via Semantic Scholar)

Single-ratio fractional integer programs with stochastic right-hand sides

IISE TRANSACTIONS, 49(6), 579–592.

By: J. Zhang n & O. Ozaltin n 

Contributors: J. Zhang n & O. Özaltın n 

author keywords: Fractional integer programming; stochastic integer programming; value functions; superadditive duality
TL;DR: This work presents an equivalent value function reformulation for a class of single-ratio Fractional Integer Programs (FIPs) with stochastic right-hand sides and proposes a two-phase solution approach that can solve instances whose extensive forms have the same order of magnitude as the largest Stochastic quadratic integer programs solved in the literature.
