Spying with the Crowd

A Data-driven Method for Crowd Simulation using a Holonification Model

In this paper, we present a data-driven method for crowd simulation with holonification model. With this extra module, the accuracy of simulation will increase and it generates more realistic behaviors of agents. First, we show how to use the concept of holon in crowd simulation and how effective it is. For this reason, we use simple rules for holonification. Using real-world data, we model the...

DEPARTMENT OF ECONOMICS WORKING PAPER SERIES Spying in Multi-market Oligopolies

We consider a multimarket framework where a set of firms compete on two interrelated oligopolistic markets. Prior to competing in these markets, firms can spy on others in order to increase the quality of their product. We characterize the equilibrium espionage networks and networks that maximize social welfare under the most interesting scenario of diseconomies of scope. We find that in some s...

Spying as an Object-Oriented Programming Paradigm

We introduce spying, a novel way of programming with objects, based on capsule programming and reflective facilities. This programming style allows easy building of monitoring systems, such as tracers, debuggers. We point out three main problems related to this programming style, and propose practical solutions to some of them. We exemplify our claims with a system that performs master/slave co...
