Vehicular ad hoc networks (VANETs) are envisioned to provide promising applications and services. One critical deployment issue in VANETs is to motivate vehicles and their drivers to cooperate and contribute to packet forwarding in vehicle-to-vehicle or vehicle-to-roadside communication. In this paper, we examine this problem, analyze the drawbacks of two straightforward schemes, and present a ...

We consider 2-player games played on a finite state space for an infinite number of rounds. The games are concurrent: in each round, the two players (player 1 and player 2) choose their moves independently and simultaneously; the current state and the two moves determine the successor state. We study concurrent games with ω-regular winning conditions specified as parity objectives. We consider ...

This paper considers the possibility of collective action by the business community to counter corruption in the award of government licenses and contracts. The analogy is with contract enforcement institutions studied by economic historians and contract law scholars. The institution in this context comprises a no-bribery norm, a community system to detect violations, and a multilateral ostraci...

We show that winning the game New Age Solitaire only depends on the number of rising sequences in the deck used. The probability of winning for the special case of a new deck that is shuffled using the GSR-shuffle (and two variants) are studied. We show that this game pinpoints the Achilles heel of the GSR-shuffle as is demonstrated using the variation distance.

In this work, we extend the model of Bonabeau et al. in the case of scale-free networks. A sharp transition is observed from an egalitarian to an hierarchical society, with a very low population density threshold. The exact threshold value also depends on the network size. We find that in an hierarchical society the number of individuals with strong winning attitude is much lower than the numbe...

In this paper we discuss a way to construct a strategy of betting that can generate abnormal returns in horse race betting markets. Using the theory of discrete choice models and Generalised Additive Models one can build a model to predict the probability of a given horse winning a given race. The paper further discusses the Kelly betting system as a way of exploiting estimates of winning proba...
