Local Neutrosophic Rough Similarity Measure based tangent function

This work studies the information brought by the degree of truth, falsity, and indeterminacy Membership in the Neutrosophic set (NS) defined as a vector representation. The tangent similarity measure into the Local Neutrosophic Rough set (LNRS) is proposed by tangent similarity measure for NSs and is also proved with some of its properties and an algorithm is generated for the proposed approach between two LNRS. Further, the proposed similarity measure is validated with the school selection problem.
