The Majority Rule Sorting (MR-Sort) method assigns alternatives evaluated on multiple criteria to one of the predefined ordered categories. The Inverse MR-Sort problem (Inv-MR-Sort) consists in computing MR-Sort parameters that match a dataset. Although Inv-MR-Sort is known to be computationally difficult, exact resolution approaches have been proposed in the literature, but are confronted to a computational barrier. In contrast, Sobrie et al. [12] tackled it with a heuristic. In this work, we aim at improving the computational efficiency of this heuristic approach by parallelization strategies using GPU.
