When Orville Wright flew his airplane over a small stretch of rolling grassland in 1903, the managing editor of Scientific American predicted that thousands of planes would soon fly over every city, delivering patrons to theaters. On the eve of the First World War, two famous British aviators argued that planes would prevent wars in the future (because they brought people together). Scientists,...

Traditionally quantitative games such as mean-payoff games and discount sum games have two players – one trying to maximize the payoff, the other trying to minimize it. The associated decision problem, “Can Eve (the maximizer) achieve, for example, a positive payoff?” can be thought of as one player trying to attain a payoff in the interval (0,∞). In this paper we consider the more general prob...

On the eve of Ukraine’s last several elections (2004 presidential, 2006 and 2007 parliamentary), observers typically described elections in breathtaking terms: “decisive,” “crucial,” “the final battle.” However, this year’s presidential election confirms the truism that if a democratic order is in place, nothing in politics is final: every decisive election is followed by another just as decisi...

Twenty years ago, on the eve of the first of the great post-BrettonWoods recessions, unemployment did not appear to be a major problem for advanced economies. Among what would later be dubbed the G-7 nations, the United States had the highest unemployment rate at 5.5 percent; but very little of this unemployment was long-term, and the extent of short-term unemployment could be rationalized as t...

This paper presents research leading to the development of Easy with Eve, an Affective Tutoring System (ATS) in the domain of primary school mathematics. The system adapts to students via a lifelike animated agent called Eve, who is able to detect student emotion through facial expression analysis, and can display emotion herself. Eve’s tutoring adaptations are guided by a case-based method for...

The actual content of games is an understudied area in social scientific research about digital interactive games (DIGs). This paper aims to contribute to the understanding of game content, in particular with respect to the portrayal of men, women, and people of different ethnic origin. Earlier studies by Provenzo [14], Gailey [8], and Dietz [6] concluded that games were dominated by stereotypi...

Suppose Alice sends an encrypted message to Bob c = Ek(m), where m is the plaintext message, c is the ciphertext and E is the encryption with respect to key k. If an eavesdropper Eve intercepts the message, knowing the encryption and decryption schemes but not the key, how much can Eve learn about m? We formalize this using two measures of security: indistinguishability of encryptions and seman...

In this paper, we study the problem of minimizing regret in discounted-sum games played on weighted game graphs. We give algorithms for the general problem of computing the minimal regret of the controller (Eve) as well as several variants depending on which strategies the environment (Adam) is permitted to use. We also consider the problem of synthesizing regret-free strategies for Eve in each...
