By us- ing , we make the quotient hyper pseudo BCK-algebra. Finally, by applying the concept of fundamental on pseudo BCK-algebra, we prove that any pseudo BCK-algebra is fundamental.https://jhs.uma.ac.ir/article_2671_a2b640712325f5e3fa5392d898019adb.pdfUniversity of Mohaghegh ArdabiliJournal of Hyperstructures2251-84365220161201On fuzzy prime and fuzzy semiprime ideals of {hypergroupoids108114267210.22098/jhs.2016.2672ENNioviKehayopuluDepartment of Mathematics, University of Athens, 15784 Panepistimiopolis, Athens,

We have showed that any given set H is a hyperstructure with And and Or operations in soft set theory. Furthermore, for any given algebraic structure (H; ), we have cre- ated hyperstructure using soft set operation which mentioned by Molodtsov [8] and binary operation .https://jhs.uma.ac.ir/article_2673_138140b331117caba57d4ff3d9b194f7.pdfUniversity of Mohaghegh ArdabiliJournal of Hyperstructures2251-84365220161201The connection of hyper lattice implication algebras and related hyper algebras124140267410.22098/jhs.2016.2674ENShokoofehGhorbaniShahid Bahonar University of KermanJournal Article20161027In this paper, we de ne the concepts of (good) con- gruences and strong congruences on hyper lattice implication alge- bras and use them to construct quotient hyper lattice implication algebras.

Some metric character- izations and sucient conditions for these types of well-posedness are obtained. Moreover, we prove that the well-posedness of gen- eralized equilibrium problems is equivalent to the existence and uniqueness of its solution.https://jhs.uma.ac.ir/article_2676_8bc6b84859663d32e931e040c1bf73ef.pdfUniversity of Mohaghegh ArdabiliJournal of Hyperstructures2251-84365220161201A novel metaheuristic for optimization inspired by mother-infant communication in animal colonies169181267710.22098/jhs.2016.2677ENAlirezaGhaffari-HadighehAzarbaijan Shahid Madani UniversityJournal Article20160826Mother-infant vocalization from distance in some animal species such as bats, gulls and penguins is a basic tool to nd the other's location. It is referred to echolocation or bio-sonar characteristics which is important for the mother to nd exactly its own baby in a large colony. Moreover, the baby uses it to better conduction the mother in getting back to the nest without knowing its exact location. This natural fact is the motivation of the current study to devise a novel metaheuristic algorithm in solving optimization problems. The proposed methodology was tested on some continuous functions and led to promising results on convergence.https://jhs.uma.ac.ir/article_2677_408621d42ba48d6c178d38c4d727456f.pdf
