The paper proposes an exact branch-and-cut method for solving integer indefinite quadratic bilevel programs with multiple objectives at the upper level, where objectives at both levels are products of two linear functions. The method replaces the upper-level indefinite quadratic terms with their two linear components to obtain a multiobjective integer linear problem solved via branch and bound for integer variables, then tests candidate integer solutions for lower-level optimality using IBM CPLEX 12.8. It uses a two-phase approach: first solving single-objective-at-both-levels cases using the d’Agnestzig cut, then adding an efficient cut strategy to enumerate a set of efficient solutions without listing the full integer domain. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

This paper proposes an exact method to solve an integer indefinite quadratic bilevel problem with multiple objectives at the upper level, where the objective functions at both levels are a product of two linear functions. The suggested algorithm uses a branch and cut algorithm based on a multiobjective integer linear problem obtained by replacing the indefinite quadratic objectives of the upper level by their two linear functions and the classical branch and bound technique for integer decision variables. Then, the integer solutions obtained are tested for optimality of the lower level problem by using a library IBM CPLEX 12.8 for C++ programs. The integer indefinite quadratic bilevel programming problem with single objective at both levels is solved in the first step, based on the dantzig cut. The second phase explorates with the efficient cut to provide the set of efficient solutions without listing the whole integer domain. After the presentation of the algorithm, a numerical example and computational experiments are provided.
