当两种食物来源在黑暗中呈现给黏菌绒泡菌时，就会形成一个用于吸收营养的粗管，通过最短的路线连接食物来源。然而，当避光生物被部分照亮时，连接食物源的管道遵循不同的路线。定义风险为实验可测量的光回避运动的速率，最小风险路径由生物体展示，通过沿路径沿着积分确定。
When two food sources are presented to the slime mold Physarum in the dark, a thick tube for absorbing nutrients is formed that connects the food sources through the shortest route. When the light-avoiding organism is partially illuminated, however, the tube connecting the food sources follows a different route. Defining risk as the experimentally measurable rate of light-avoiding movement, the minimum-risk path is exhibited by the organism, determined by integrating along the path. A model for an adaptive-tube network is presented that is in good agreement with the experimental observations.
