In this article, a real-coded genetic algorithm (GA) is proposed capable of simultaneously optimizing the structure of a system (number of inputs, membership functions and rules) and tuning the parameters that define the fuzzy system. A multideme GA system is used in which various fuzzy systems with different numbers of input variables and with different structures are jointly optimized. Commun...

urban parks have essential role in public welfare. their role could be observed in personal, socio-economic, environmental and mental wellbeing. provision of socio-mental needs of citizens and enhancement of social cohesion are contributed to the way of using urban open and green spaces which such issue requires elaborated planning and design. equal access to parks is an important issue in dist...

Obtaining a weaker condition that preserves some inspired topological properties is always desirable. As result, we introduce the concept of infra-fuzzy topology, which subset family degrades fuzzy topology by omitting closedness under arbitrary unions. Fundamental spaces are investigated, including open and closed sets, interior closure operators, boundary set. It not possible to expect latter...

We introduce and study higher-order coalition logic, a multi modal monadic second-order logic with operators [{x}ψ]φ expressing that the coalition of all agents satisfying ψ(x) can achieve a state in which φ holds. We use neighborhood semantics to model extensive games of perfect information with simultaneous actions and we provide a framework reasoning about agents in the same way as it is rea...

Fuzzy rough set (FRS) has a great effect on data mining processes and the fuzzy logical operators play key role in development of FRS theory. In order to generalize theory more complicated environments, we firstly propose four types neighborhood based covering by overlap functions their implicators this paper. Meanwhile, derived coverings from an original are defined equalities among function-b...
