In this paper, we deal with two-person zero-sum games fuzzy goals. We investigated the cases where membership functions of players are nonlinear. examined how solutions should be if were exponential functions. case players' exponential, developed a new method for maximin solution according to degree attainment An application was made show effectiveness method.

in this paper, our focus of attention is the proper propagationof fuzzy degrees in determinization of $nondeterministic$ $fuzzy$$finite$ $tree$ $automata$ (nffta). initially, two determinizationmethods are introduced which have some limitations (one inbehavior preserving and other in type of fuzzy operations). inorder to eliminate these limitations and increasing theefficiency of ffta, we defin...

In this paper we propose a notion of weak bisimulation for a class of weighted automata with unobservable transitions where weights are taken from an idempotent semiring. In particular the (max/+), (min/+) or (max/min) dioid are considered. The proposed bisimulation is a natural extension of Milner’s well known weak bisimulation for untimed automata (i. e., weighted automata over the boolean se...

The conventional fuzzy set model uses the MIN and MAX operators for the evaluation of boolean operators AND and OR, respectively. It has been criticized to generate incorrect ranked output in many cases. This is because the MIN and MAX operators do not well correspond with human behavior for document ranking. There are a variety of fuzzy operators to replace the MIN and MAX operators. In this p...

This paper is devoted to the survey of some automata-theoretic aspects of diierent exotic semirings, i.e. semirings whose underlying set is some subset of R equiped with min, max or + as sum and/or product. We here adress three types of properties related with rational series with multiplicities in such semirings : structure of supports, decidability of equality and inequality problems, Fatou p...
