Алгоритмы расчета точных значений индексов манипулируемости для случая трех альтернатив

Abstract. Manipulation is a phenomenon when an agent or a group of agents misrepresent her/their preferences in the ballots in order to obtain a better outcome of the social choice. It has been proven that there is no not-dictatorial social choice rule which is nonmanipulable. There are two approaches to fi nd the least manipulable social choice rules. The fi rst one implies fi nding a theoretical formula for each rule. However, there are many known social choice rules and a list of manipulability indices which make this task very hard. The second approach is to generate a set of random profi les to obtain an approximate values of manipulability indices. We developed an algorithm which allows to get not approximate, but exact values of manipulability indices for any given social choice for the case of 3 alternatives. We provide the description of the algorithm, its optimizations, memory and time needed compared to the previously known algorithms, as well as the examples of the results.

Open access to images creates opportunities for violation of the authors' rights. Digital watermarks can be used to securely publish images online. They are invisibly added into the images before publication and can be extracted at any time to verify ownership. However, achieving a balance between embedding imperceptibility and robustness to image processing operations is ...

A volatility forecast becomes useful only after it has passed through four stages: a model produces it, a trading rule consumes it, a portfolio aggregates the result, and an investor evaluates that result against a utility function. Each stage has its own mature evaluation apparatus, and each is studied in isolation. This review traces the ...

This study investigates gender‑based disparities in viewership and prize money within Counter‑Strike: Global Offensive competitions, using data from the ESL Impact League (female‑only) and comparable male leagues. Because esports performance depends chiefly on strategic choices and fine motor skills rather than physical strength, this setting offers a distinctive lens for examining gender equity where bodily ...

В основе принятия своевременных экономико-политических решений и бизнес-планирования лежит мониторинг текущей ситуации и прогнозирование путей развития экономической активности, базу которых составляют официальные статистические оценки значений различных показателей. В этой связи переоценка данных и прогнозы, основанные на более ранних либо поздних оценках, потенциально могут повлечь за собой совершенно различные экономико-политические решения. Согласно официальной методике Росстата, публикуется ...

Electronic health records (EHRs) contain vast volumes of clinical information that encode complex relationships between diseases. Traditional approaches to the analysis of interrelated or co-occurring diseases have focused on pairwise associations between diagnoses, missing the higher-order structures that characterise multimorbid patients. The present paper offers a narrative review of existing statistical, machine-learning, and artificial intelligence ...

Psychological characteristic estimation from multimodal in-the-wild behavior is usually studied using separate corpora, each annotated for a single target task. Such annotation fragmentation limits cross-task learning and cross-domain generalization across affective, dispositional, and interactional phenomena. To address this problem, we use emotion, apparent personality trait, and ambivalence recognition as representative tasks and introduce MM-PSYCHE, a ...

Hypergraphs provide a natural framework for representing neurophysiological interactions distributed across sets of sensors. A key methodological question is how hyperedges should be defined from frequency-resolved electroencephalography/magnetoencephalography (EEG/MEG) data. We demonstrate a construction strategy in which hyperedges are obtained from canonical coherence (caCOH), an extension of coherence that estimates coupling between multidimensional signal spaces. To ...

This paper asks which families of volatility forecasting models create economic value in active trading, and through which integration channel that value is transmitted. Seven models drawn from four families — econometric (GJR-GARCH, HAR-J), gradient boosting (XGBoost, LightGBM), recurrent neural networks (LSTM, GRU) and a hybrid combining HAR-J with boosting — are compared on the ...

This work presents a simulation-based comparative analysis on the harm of manipulations in two widely used school choice mechanisms – the constrained Boston and Gale-Shapley mechanisms – through the perspective of the percentage of students getting into schools and the average welfare of students. Thus, this part of the research extends the manipulability analysis presented ...

Following the change in the Chicago school admission system, Pathak and Soenmez (2013) showed that the change was justified from the manipulability perspective – the Boston mechanism, indeed, remained more manipulable than the Gale-Shapley mechanism, when students were only allowed to submit constrained preference lists (the same constraint for both mechanisms). They worked under the ...

Collective decision-making is a part of everyday life in modern society. People invented a variety of voting procedures for aggregating individual preferences into a collective choice. However, the problem is that people can misrepresent their preferences in order to achieve a more preferable voting result. This phenomenon is called manipulation and is considered negative since ...

The degree of individual manipulability of positional aggregation procedures is evaluated for the dynamic voting model within the framework of the two-dimensional Downsian model. In the dynamic voting model, alternatives move in steps toward a central point while agents attempt to manipulate at each step. The share of manipulable profiles, i.e., the Nitzan-Kelly index, is ...
