Hypersoft set is a generalization of soft sets, which takes into account a multiargument function. The main objective of this work is to introduce fuzzy semiopen and closed hypersoft sets and study some of their characterizations and also to present neutrosophic semiopen and closed hypersoft sets, an extension of fuzzy hypersoft sets, along with few basic properties. We propose two algorithms based on neutrosophic hypersoft open sets and topology to obtain optimal decisions in MAGDM. The efficiency of the algorithms proposed is demonstrated by applying them to the current COVID-19 scenario.

COVID-19情景下的中智半开放式Hypersoft集及其在MAGDM中的应用

Hypersoft集是软集的泛化，它考虑了多参数功能。这项工作的主要目的是介绍模糊半开放和封闭超软集合，并研究它们的某些特征，并提出中智半开放和封闭超软集合，这是模糊超软集合的扩展，几乎没有基本特性。我们提出了两种基于中智超软开放集和拓扑的算法，以获得MAGDM中的最佳决策。通过将算法应用于当前的COVID-19场景，可以证明所提出算法的效率。
