Enumeration Of Autocatalytic Subsystems In Large Chemical Reaction Networks
Here, we derive sufficient conditions for subgraphs supporting irreducible autocatalytic systems in the bipartite König representation of the CRN. On this basis, we develop an efficient algorithm to enumerate autocatalytic […]
