Abstract: Highlights•An adjustment factor was defined to adjust the neighborhood radius adaptively.•The PKO algorithm was introduced to find globally optimal reducts in attribute reduction.•A group-based three-way partition mechanism was proposed in PKO.•Experiments demonstrate that 3PKO-ANRAR outperforms the state-of-the-art algorithms.
