Abstract | |||||||||||
| Progress in molecular electronics is beginning to yield the technology for creating structures that incorporate myriads of nanoscale computationally active units. These could be fabricated at almost no cost, provided (1) the individual units need not all work correctly; and (2) there is no need to manufacture precise geometrical arrangements of the units or precise interconnections among them. Programming such structures to perform useful computations is a significant challenge. The objective of the research proposed here is to create foundational programming technology for reliably obtaining coherent, prespecified behavior from vast numbers of unreliable information- processing units, irregularly arranged and interconnected in unknown and even time-varying ways. Our approach combines principles for controlling complexity, drawn from computer science, with techniques for robust design, inspired by biology. | |||||||||||
