Pythagorean fuzzy sets One extension of IFS is what is known as Pythagorean fuzzy sets. Such sets satisfy the constraint , which is reminiscent of the Pythagorean theorem. Pythagorean fuzzy sets can be applicable to real life applications in which the previous condition of is not valid. However, the less restrictive condition of may be suitable in more domains.
