Complex Networks from Simple Rules
Complex networks are all around us, and they can be generated by simple mechanisms. Understanding what kinds of networks can be produced by following simple rules is therefore of great importance. This issue is investigated by studying the dynamics of extremely simple systems where a “writer” moves around a network, modifying it in a way that depends upon the writer’s surroundings. Each vertex ...
متن کاملWeathering climate change: some simple rules to guide adaptation decisions
This paper discusses some of the elements that may characterise an efficient strategy to adapt to a changing climate. Such a strategy will have to reflect the long time horizon of, and the prevailing uncertainties about, climate change. An intuitively appealing approach therefore seems to be to enhance the flexibility and resilience of systems to react to and cope with climate shocks and extrem...
متن کاملSimple Ecological Rules Yield Complex Agent Networks
In complex natural systems (such as ecological systems) it is common for those studying the macro-dynamics of systems to aim to describe, as simply as possible, the interactions between individuals occupying different niches in a system and to validate these by studying whether they account for the complex network of relationships observed in the actual system. We explore a similar principle ap...
متن کاملSimple versus complex selection rules for forecasting many time series
A major problem for many organisational forecasters is to choose the appropriate forecasting method for a large number of time series. Various selection rules have been proposed in order to enhance forecasting accuracy. The simpler approach for model selection involves the identification of a single method, which is applied to all data series in an aggregate manner, without taking into account ...
متن کاملSimple rules for passive diffusion through the nuclear pore complex
Passive macromolecular diffusion through nuclear pore complexes (NPCs) is thought to decrease dramatically beyond a 30-60-kD size threshold. Using thousands of independent time-resolved fluorescence microscopy measurements in vivo, we show that the NPC lacks such a firm size threshold; instead, it forms a soft barrier to passive diffusion that intensifies gradually with increasing molecular mas...
