摘要

传统的串行电子处理器的信息处理消耗了全球不断增长的电力供应。另一种高能效的并行计算范式是基于网络的生物计算(NBC)。在NBC中,一个给定的组合问题被编码到一个纳米制造的模块化网络中。通过大量独立的分子马达驱动蛋白细丝对网络进行并行探索,解决了编码问题。在这里,我们通过解决四个实例的精确覆盖(一个应用于资源调度的非确定性多项式时间(NP)完全问题)来展示该技术的显著扩展。这里解决的最大实例的难度是NBC当前技术水平的128倍。

Solving Exact Cover Instances with Molecular-Motor-Powered Network-Based Biocomputation

Information processing by traditional, serial electronic processors consumes an ever-increasing part of the global electricity supply. An alternative, highly energy efficient, parallel computing paradigm is network-based biocomputation (NBC). In NBC a given combinatorial problem is encoded into a nanofabricated, modular network. Parallel exploration of the network by a very large number of independent molecular-motor-propelled protein filaments solves the encoded problem. Here we demonstrate a significant scale-up of this technology by solving four instances of Exact Cover, a nondeterministic polynomial time (NP) complete problem with applications in resource scheduling. The difficulty of the largest instances solved here is 128 times greater in comparison to the current state of the art for NBC.
