Creation vs. Evolution

7. Evolution and Creation

Many consider that Evolution and Creation are alternatives and therefore that one must make a choice between these two explanations of the natural world. This difficulty has dogged the debate since Darwin presented his explanation of the multiplicity and development of species in the 19th C. and even before. The issue has therefore become polarised and often the subject of bitter controversy. H...

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...
