Soft set theory was proposed by Molodtsov in 1999, as a generalization of fuzzy set theory to deal with uncertainty in a parametric manner. This particular theory have many applications in decision making problems and therefore attracted many mathematicians, physicists, and engineers. This book devotes the concept of uni-soft ideals in the field of Abel-Grassmann groupoid (or simply AG-groupoid). This book provides the notions of uni-soft AG-groupoids, uni-soft left(right) ideals, uni-soft quasi ideals, uni-soft bi-ideals and uni-soft interior ideals of AG-groupoids and also discuss some interesting characterizations of these Ideals. Hopefully, this book will helps the reader to extend these notions to the emerging algebraic structures of AG-gorupoids such as, rings, semirings, G-semigroups and G-AG-groupoids.
