Resource-Based Models of Mutualism

Evolutionary Models of Mutualism

models of dynamic resource allocation

in dea to obtain an efficient representation in ccr andbcc models for each dmu only one linear plan would be solved; however,it is possible in centralized resource allocation (cra) to solve allthe dmus by one linear planning. in this paper, models of centralizedresource allocation in input-oriented and in dynamic case will be offeredand by using dynamic sbm, the representation of dmus in each t...

Economic contract theory tests models of mutualism.

Although mutualisms are common in all ecological communities and have played key roles in the diversification of life, our current understanding of the evolution of cooperation applies mostly to social behavior within a species. A central question is whether mutualisms persist because hosts have evolved costly punishment of cheaters. Here, we use the economic theory of employment contracts to f...

Resource Based Models for Asynchrony

form. The key to our choice of morphism lies in understanding internal actions as a pair of unspeci ed synchronising actions, hidden from the environment. One may like to think of pre xing as syntactic sugar for a:(a! k a?P ): We consider what e ects specifying a name, a, for these actions, and allowing them to be seen by the environment, has; call this speci ed synchronising pair a, so one mig...

Explaining Resource Undermatching with Agent-Based Models

We propose two agent-based models of group foraging for two perceptual conditions. These models exhibit complex group-level behavior using only a simple rule set with a homogeneous group of agents. The models are shown to replicate results from Goldstone and Ashpole (2004), and we describe a series of simulations that test the sources of the resource undermatching often found in group foraging ...
