Hypergraphs Based on Pythagorean Fuzzy Soft Model

  • Gulfam Shahzadi and
  • Muhammad Akram

23 November 2019

A Pythagorean fuzzy soft set (PFSS) model is an extension of an intuitionistic fuzzy soft set (IFSS) model to deal with vague knowledge according to different parameters. The PFSS model is a more powerful tool for expressing uncertain information whe...
