Review: a generalized belief interval-valued soft set with applications in decision making

The paper named "A generalized belief interval-valued soft set with applications in decision making", published in the Soft Computing Journal volume 24 pages 9339-9350 (Cheng et al. 2020), proposed a generalized belief interval-valued soft set approach and explored the associated properties of this approach in decision-making applications with using score function. We have identified some deficiencies, which is affecting the clearness and clarity of the study in the mathematical expressions of some definitions in the article. So in this paper we discuss these kinds of deficiencies, which is really essential for intelligibility and definiteness of the study.
