Comparison of combustion chemistries and random networks (null model).

Values in brackets are the standard error of the mean (SEM). The analyzed combustion chemistries show no semantic capacity. This is supported by the analysis of random networks of the same size and density. The low number of codes found in these random networks can be explained by the noise of the random network generation. Number of random networks: , for DME the calculation was not feasible. All networks have been analyzed with the pathways based algorithm with . The number of paths in MET, ETH, DME has been estimated by counting paths with growing values of k. The maximal computable value gives a lower bound.
