摘要翻译：
我们提出了一种特殊的计算装置，它利用光线来解决子集和问题。该设备有一个类似图形的表示，光线通过遵循节点之间的连接给出的路线来穿过它。节点以一种特殊的方式由弧连接，这使得我们可以生成给定集合的所有可能的子集。对于每个弧，我们要么从给定的集合中分配一个数字，要么分配一个预定义的常数。当光线通过一个弧时，它被延迟了由放置在该弧中的数字所指示的时间量。在目的节点，我们将检查是否有一条射线的总延迟等于子集和问题的目标值（加上一些常数）。

英文摘要：
  We propose a special computational device which uses light rays for solving the subset-sum problem. The device has a graph-like representation and the light is traversing it by following the routes given by the connections between nodes. The nodes are connected by arcs in a special way which lets us to generate all possible subsets of the given set. To each arc we assign either a number from the given set or a predefined constant. When the light is passing through an arc it is delayed by the amount of time indicated by the number placed in that arc. At the destination node we will check if there is a ray whose total delay is equal to the target value of the subset sum problem (plus some constants).
