Abstract: Fermatean fuzzy set is a special extensional fuzzy set which generalises both intuitionistic fuzzy set and Pythagorean fuzzy set by expanding the spatial scope of Pythagorean fuzzy sets and intuitionistic fuzzy sets. Similarity measure is an integral aspect of utilising generalised fuzzy sets in soft computing. In this paper, a novel similarity measure between Fermatean fuzzy sets is introduced with a better and reliable output compare to the dual of the existing Fermatean fuzzy distance measure. Some properties of the new similarity measure are characterised. It is demonstrated that the new similarity measure between Fermatean fuzzy sets is more reliable than the dual of the existing Fermatean fuzzy distance measure. In terms of application, the new Fermatean fuzzy similarity measure is utilised in executing students' admission process using an algorithmic approach implemented by a programming language to enhance accuracy and ease of computations.
