Improvement of Fire Extinguishing Performance by Decentralized Supply of Fire-Fighting Agents

Fighting Fire with Agents

In this paper we propose a model for coordinating teams of computational agents. This model is especially aimed for coordinating agents performing in a simulated environment of forest firefighting, although it may be used in other domains. We will start by introducing the Pyrosim platform where we are carrying out our experiments. Pyrosim is a tool developed in our laboratory that simulates a f...

DoS: Fighting Fire with Fire

We consider DoS attacks on servers in which attackers’ requests are indistinguishable from legitimate requests. Most current defenses against this class of attack rely on legitimate users in aggregate having more of some resource (CPU cycles, memory cycles, human attention, etc.) than attackers. A server so defended asks prospective clients to prove their legitimacy by spending some of this res...

Eradication of poliovirus: fighting fire with fire.

Endemic wild polioviruses have been eliminated from most of the world, and the number of human paralytic cases has been reduced by .99%, from an estimated annual incidence of .500,000 cases to ,2000 cases [1–3]. Circulating wild polioviruses remain endemic in only 2 major locations, Nigeria and a zone extending from northern India west to Pakistan and Afghanistan [1–3]. Furthermore, wild-type 2...

Evolutionary Learning of Fire Fighting Strategies

The dynamic problem of enclosing an expanding fire can be modelled by a discrete variant in a grid graph. While the fire expands to all neighbouring cells in any time step, the fire fighter is allowed to block c cells in the average outside the fire in the same time interval. It was shown that the success of the fire fighter is guaranteed for c > 1.5 but no strategy can enclose the fire for c ≤...
