Abstract

For a given partial solution,the partial inverse problem is to modify the coefficientssuch that there is a full solution containing the partial solution, while the full solution becomes optimal under new coefficients, and the total modification is minimum.In this paper, we show that the partial inverseassignment problem and the partial inverse minimum cut problem are NP-hard ifthere are bound constraints on the changes of coefficients.

Keywords
