While voting systems were originally used in political science, they are now also of central importance in various areas of computer science, such as artificial intelligence (in particular within multiagent systems). Brams and Sanver [BS06] introduced sincere-strategy preference-based approval voting (SP-AV) and fallback voting (FV), two election systems which combine the preference rankings of...

We study the computational complexity of committee selection problem for several approval-based voting rules in the presence of outliers. Our first result shows that outlier consideration makes committee selection problem intractable for approval, net approval, and minisum approval voting rules. We then study parameterized complexity of this problem with five natural parameters, namely the targ...

Memory-based collaborative filtering is the most popular approach to build recommender systems. Despite its success in many applications, it still suffers from several major limitations, including data sparsity. Sparse data affect the quality of the user similarity measurement and consequently the quality of the recommender system. In this paper, we propose a novel user similarity measure based...

This article offers an E-voting (Electronic Voting) approach that ensures security, privacy, and transparency. We have decided to use the blockchain system. Blockchain technology lowers cost of centralized Clouds, Datacenters, Networking Equipment, decreases need for middlemen, provides data privacy transparency; all which are critical a fair election.An Architecture Algorithm suggested blockch...

In this study, we introduced a probabilistic voter, regarding symbol probabilities in decision process besides majority consensus. Conventional majority voter is independent of functionality of redundant modules. In our study, proposed probabilistic voter is designed corresponding to functionality of the redundant module. We tested probabilistic voter for 3 and 5 redundant modules with random t...

Trembling hand (TH) equilibria were introduced by Selten in 1975. Intuitively, these are Nash equilibria that remain stable when players assume that there is a small probability that other players will choose off-equilibrium strategies. This concept is useful for equilibrium refinement, i.e., selecting the most plausible Nash equilibria when the set of all Nash equilibria can be very large, as ...

Voting algorithms, such as histogram and Hough transforms, are frequently used algorithms in various domains, such as statistics and image processing. Algorithms in these domains may be accelerated using GPUs. Implementing voting algorithms efficiently on a GPU however is far from trivial due to irregularities and unpredictable memory accesses. Existing GPU implementations therefore target only...

Voting is used in realizing ultrareliable systems based on multichannel computation. In practical applications to date, the multiple computation channels have consisted of identical hardware circuits, which are expected to produce the same outputs, or diverse software modules, which may produce inexact or incomplete results. The challenge in hardware voting is the choice of adjudication points ...

Many consensus clustering methods have been applied in different areas such as pattern recognition, machine learning, information theory and bioinformatics. However, few methods have been used for chemical compounds clustering. In this paper, an information theory and voting based algorithm (Adaptive Cumulative Voting-based Aggregation Algorithm A-CVAA) was examined for combining multiple clust...
