Such a ‘sum over computations’ encompasses both regular and random architectures within its superposition, and weighs computations according to the length of the program to which they correspond: algorithmically simple computations that arise from short programs have higher weight. The observational consequences of this and other candidate computations will be the subject of future work. @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
