In cooperatively-breeding species, the sexes of subordinate group members may have important consequences for dominant individuals. We varied subordinates’ sexes in aquariumhoused groups of the cooperatively-breeding cichlid fish Neolamprologus pulcher, and compared the behaviours of dominant individuals in groups with sameversus oppositesex subordinates. Dominants tended to be more aggressive ...

This paper introduces a mechanism for computing approximations of Dominance-Based Rough Sets (DBRS) by bit-vector encodings. DBRS was introduced by Greco et al. as an extension of Pawlak’s classical rough sets theory by using dominance relations in place of equivalence relations for approximating sets of preference ordered decision classes. Our formulation of dominance-based approximation space...

Incremental induction of decision rules within the dominance-based rough set approach to the multicriteria and multiattribute classification is discussed. We introduce an algorithm, called Glance, that incrementally induces a set of all rules from examples. We experimentally evaluate it and compare with two other algorithms, previously proposed for this kind of classification problem.

Induction of decision rules within the dominance-based rough set approach to the multiple-criteria sorting decision problem is discussed in this paper. We introduce an algorithm called DOMLEM that induces a minimal set of generalized decision rules consistent with the dominance principle. An extension of this algorithm for a variable consistency model of dominance based rough set approach is al...

The standard RSA cryptosystem is not semantically secure. Pointcheviel proposed a variant of RSA cryptosystem with the property of semantic security by introducing a new problem known as DRSA problem. He called it DRSA scheme. In this paper, we underlined a shortcoming of that scheme and proposed an alternative DRSA public key cryptosystem.

One of the primary differences between humans and other animals is our capacity for high level cognition and the use of language. Historically, AI has understandably focused on duplicating these aspects of human behavior, and selected its architectures accordingly. However, humans are nevertheless social mammals and share a large part of the mammalian behavior repertoire, such as feeding, as we...

Dominance measuring methods are a recent approach for dealing with complex decisionmaking problems with imprecise, incomplete or partial information within multi-attribute value/utility theory. These methods compute pairwise dominance values and exploit the information included in the dominance matrix in different ways to derive measures of dominance intensity to rank the alternatives under con...

The paper investigates relationships between chemical structure, surface active properties and antibacterial activity of 70 bis-quaternary imidazolium chlorides. Chemical structure and properties of imidazolium chlorides were described by 7 condition attributes and antimicrobial properties were mapped by a decision attribute. Dominance-based Rough Set Approach (DRSA) was applied to discover a p...
