Nondifferentiable multiobjective programming under generalized dI-invexity
TLDR
In this paper, we are concerned with a nondifferentiable multiobjective programming problem with inequality constraints in which each component of the objective and constraint functions is directionally differentiable in its own direction di. Expand

A very fast and robust trust inference algorithm in weighted signed social networks using controversy, eclecticism, and reciprocity
TLDR
We show in this paper that trust and distrust can be quickly predicted using some social traits of the trustor and the trustee using a "tug of war" analogy involving these traits. Expand

Desertification in the Maghreb: A Case Study of an Algerian High-Plain Steppe
Natural and semi-natural ecosystems of the Maghreb have been subject, for several centuries, to grazing and cultivation as dominant land-uses. Living in a Mediterranean climate which is generallyExpand

A robust trust inference algorithm in weighted signed social networks based on collaborative filtering and agreement as a similarity metric
TLDR
We propose a new unsupervised trust inference algorithm based on collaborative filtering (CF), where we consider the trustors as users, the trustees as items, and agreement as a local similarity metric to predict trust values in signed, and unsigned, networks. Expand

Saturated boundary k-alliances in graphs
TLDR
We study mathematical properties of (global) saturated boundary defensive, offensive and powerful k -alliances and theoretical results are obtained by giving tight bounds and exact values on the cardinality of such alliances. Expand

A distributed authentication model for composite Web services
TLDR
We propose a distributed model of authentication based on the circle of trust concept for composite Web services. Expand

Alliances in graphs: Parameters, properties and applications - A survey
TLDR
We present a survey which covers a number of practical applications of alliances and the vast mathematical properties of the three types of k -alliances by giving a special attention to the study of the associated kalliance (partition) numbers for different graph classes. Expand
