The most popular approach to decision-making in the setting of fuzzy sets is the maximin ranking of solutions. This method is natural when interpreting the fuzzy sets as flexible constraints that cannot compensate with one another. However the obtained ranking of solutions is very coarse. Two kinds of refinements to this ordering are introduced: a partial ordering according to the least satisfi...

Qualitative decision tools have been used in AI and CS in various contexts, but their adequacyis still unclear. To examine this question, our work employs the axiomatic approach to characterize the properties of various decision rules. In the past, we presented a constructive representation theorem for the maximin decision criterion, and we characterized conditions under which an agent can be v...

In this chapter, we will study the computational complexity of manipuation for three common voting rules. We will prove that the unweighted coalitional manipulation problem (Definition 3.1.2) is NP-complete for maximin (Section 4.1) and ranked pairs (Section 4.2), and we will give a polynomial-time algorithm for UCM for Bucklin (Section 4.3). 4.1 Manipulation for Maximin is NP-complete In this ...

We propose three operators based on MFF. The first uses MFF. The second uses MFF when applies Maximin-Constraint and uses modified MFF when applies Maximin-Clustering. The third uses modified MFF. According to the results, the three operators are competitive to solve multi-objective optimization problems having both low dimensionality (two or three) and high dimensionality (more than three) in ...

We concentrate on discussing a class of two-person zero-sum games with rough payoffs. Based on the expected value operator and the trust measure of rough variables, the expected equilibrium strategy and r-trust maximin equilibrium strategy are defined. Five cases whether the game exists r-trust maximin equilibrium strategy are discussed, and the technique of genetic algorithm is applied to find...

Regular environmental conditions allow for the evolution of specifically adapted responses, whereas complex environments usually lead to conflicting requirements upon the organism's response. A relevant instance of these issues is bacterial chemotaxis, where the evolutionary and functional reasons for the experimentally observed response to chemoattractants remain a riddle. Sensing and motility...
