Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...

If several physical theories are consistent with the same experimental data which theory should we choose Physicists often choose the simplest theory this principle explicitly formulated by Occam is one of the basic principles of physical reasoning However until recently this principle was mainly a heuristic because it uses the informal notion of simplicity With the explicit notion of simplicit...

Abstract The number of adjustable parameters in a model or hypothesis is often taken as the formal expression its simplicity. I take issue with this `definition´ and argue that comparative simplicity has quasi-empirical measure, reflecting experts’ judgements who track past use model-type across domains. Since models are represented by restricted sets functions suitable space, formally speaking...
