Plasmodium of a cellular slime mould Physarum polycephalum is a unique living substrate proved to be efficient in solving many computational problems with natural spatial parallelism. The plasmodium solves a problem represented by a configuration of source of nutrients by building an efficient foraging and intra-cellular transportation network. The transportation networks developed by the plasmodium are similar to transport networks built by social insects and simulated trails in multi-agent societies. In the paper we are attempting to answer the question "How close plasmodium of P. polycephalum approximates man-made motorway networks in Spain and Portugal, and what are the differences between existing motorway structure and plasmodium network of protoplasmic tubes?". We cut agar plates in a shape of Iberian peninsula, place oat flakes at the sites of major urban areas and analyse the foraging network developed. We compare the plasmodium network with principle motorways and also analyse man-made and plasmodium networks in a framework of planar proximity graphs.
多头绒泡菌这种细胞黏菌的原质团是一种独特的活体基质，已被证明能有效地利用自然空间并行性解决许多计算问题。原质团通过构建高效的觅食和细胞内运输网络来解决由营养源配置所代表的问题。原质团形成的运输网络类似于社会性昆虫构建的运输网络以及多智能体社会中模拟的踪迹。在本文中，我们试图回答“多头绒泡菌的原质团与西班牙和葡萄牙的人造高速公路网络有多相似，以及现有高速公路结构与原生质管的原质团网络之间有哪些差异？”这个问题。我们将琼脂板切割成伊比利亚半岛的形状，在主要城市区域放置燕麦片，并分析形成的觅食网络。我们将原质团网络与主要高速公路进行比较，并在平面邻近图的框架内分析人造网络和原质团网络。
