Schlaussimmer in Reichsautobahnen:Slime mould implies motorway network in Germany
Schlauschleimer in Reichsautobahnen: Slime mould imitates motorway network in Germany
摘要:
德国高速公路的特点是悠久的传统,细致的国家规划,西德和东德交通网络之间的历史不平衡,以及现代欧洲交通量的最高增长,需要扩建和/或重组。我们尝试在多头绒泡菌黏菌实验中,利用生物网络的内在最优性原理来评估autobahns的结构。在实验室实验与活的黏菌,我们代表德国的主要城市地区的营养来源,接种在柏林的黏菌,等到黏菌殖民所有主要城市地区和比较原生质网络的统计结构与现有的高速公路网络。利用图的积分特征和指数对黏菌图和高速公路图进行了直观的比较分析。我们还研究了平面邻近图的背景下的原生质和autobahn网络。
英文摘要:
The German motorway, or 'autobahn', is characterised by long traditions, meticulous state planning, historical misbalance between West and East Germany's transport networks, and highest increase in traffic in modern Europe, posing a need for expansion and/or restructuring. We attempt to evaluate the structure of autobahns using principles of intrinsic optimality of biological networks in experiments with slime mould of Physarum polycephalum. In laboratory experiments with living slime mould we represent major urban areas of Germany with sources of nutrients, inoculate the slime mould in Berlin, wait till the slime mould colonises all major urban areas and compare the statistical structure of protoplasmic networks with existing autobahn network. The straightforward comparative analysis of the slime mould and autobahn graphs is supported by integral characteristics and indices of the graphs. We also study the protoplasmic and autobahn networks in the context of planar proximity graphs.
