Riding with the ants

Riding with the ants

Isolates of Teratosphaeriaceae have frequently been found in the integument of attine ants, proving to be common and diverse in this microenvironment. The LSU phylogeny of the ant-isolated strains studied revealed that they cluster in two main lineages. The first was associated with the genus Xenopenidiella whereas the other represented two ant-isolated lineages sister to the taxa Penidiella ag...

Dynamic Free Riding with Irreversible

We study the Markov equilibria of a model of free riding in which n infinitely lived agents choose between private consumption and irreversible contributions to a durable public good. We show that the set of equilibrium steady states converges to a unique point as depreciation converges to zero. For any level of depreciation, moreover, the steady state of the best Markov equilibrium converges t...

Leading The Ignorant: Can Ignorance Eliminate The Free Riding Problem?

Overcoming Obstacles with Ants

Consider a group of mobile finite automata, referred to as agents, located in the origin of an infinite grid. The grid is occupied by obstacles, i.e., sets of cells that can not be entered by the agents. In every step, an agent can sense the states of the co-located agents and is allowed to move to any neighboring cell of the grid not blocked by an obstacle. We assume that the circumference of ...

Query Routing with Ants?

In this paper we propose SemAnt, a novel ant-based algorithm designed for query routing in taxonomy-based peer-to-peer environments. We introduce the reader to the pheronome trail-laying-andfollowing behaviour observed from natural ants and show how it can be applied to query routing in peer-to-peer networks. Our proposed algorithm accounts for network parameters such as bandwidth and latency a...
