Imitation vs. Creation

Creation of DEVS models using imitation learning

Modelling and simulation of robotic control systems allows for low cost analysis and experimentation. However, creating these models requires a level of technical expertise. To improve the technical quality of such models, we propose a case-based reasoning approach to learn the behaviour of models using the DEVS formalism. By observing a desired behaviour, in the form of outputs produced in res...

Creation vs. Evolution

The trouble with memes : Inference versus imitation in cultural creation.

Memes are hypothetical cultural units passed on by imitation; although nonbiological, they undergo Darwinian selection like genes. Cognitive study of multimodular human minds undermines memetics: unlike in genetic replication, high-fidelity transmission of cultural information is the exception, not the rule. Constant, rapid "mutation" of information during communication generates endlessly vari...

Selfish vs. Unselfish Optimization of Network Creation

We investigate several variants of a network creation model: a group of agents builds up a network between them while trying to keep the costs of this network small. The cost function consists of two addends, namely (i) a constant amount for each edge an agent buys and (ii) the minimum number of hops it takes sending messages to other agents. Despite the simplicity of this model, various comple...

Network Creation Games: Structure vs Anarchy

We study Nash equilibria and the price of anarchy in the classical model of Network Creation Games introduced by Fabrikant et al. In this model every agent (node) buys links at a prefixed price $\alpha>0$ in order to get connected to the network formed by all the $n$ agents. In this setting, the reformulated tree conjecture states that for $\alpha>n$, every Nash equilibrium network is a tree. S...
