黏菌逻辑门：探索弹道方法
Slime mould logical gates: exploring ballistic approach
摘要：
\emph{Physarum polycephalum}的疟原虫是一种肉眼可见的单细胞。在无营养的基质上，原质团作为一种移动的定位，作为原生质的一种紧凑的波形碎片进行繁殖。即使不存在化学引诱剂的梯度，疟原虫定位也在其最初预定的方向上行进相当长的一段时间。利用\emph{Physarum}局部化的这一性质，我们设计了两输入两输出布尔逻辑门$<x, y> \to <xy, x+y>$和$<x, y> \to <x, bar{x}y>$。我们在实验室实验和计算机模拟验证的设计。我们将逻辑门级联成一位半加器，并对其功能进行了仿真。
英文摘要：
Plasmodium of \emph{Physarum polycephalum} is a single cell visible by unaided eye. On a non-nutrient substrate the plasmodium propagates as a traveling localization, as a compact wave-fragment of protoplasm. The plasmodium-localization travels in its originally predetermined direction for a substantial period of time even when no gradient of chemo-attractants is present. We utilize this property of \emph{Physarum} localizations to design a two-input two-output Boolean logic gates $<x, y> \to <xy, x+y>$ and $<x, y> \to <x, bar{x}y>$. We verify the designs in laboratory experiments and computer simulations. We cascade the logical gates into one-bit half-adder and simulate its functionality.
