Consolidation-disruption index (CD index) is a metric for qualitatively measuring the contribution of a patent or a research paper. Since its inception, a plethora of experimental studies have been undertaken to explore this index. We embark on the study of the complexity of CD index manipulation problems, which model scenarios where a scholar aims to enhance the CD indices of their papers through merging, adding, or removing papers. We show that these problems are computationally hard, even when restricted to very realistic special cases. Additionally, we explore how different parameters influence the parameterized complexity of these problems.
