Thermodynamic ranking of pathways in reaction networks
Chemical Reaction Networks (CRNs) provide a powerful framework for modeling complex systems due to their compositionality, which makes them well-suited for analyzing interactions of subsystems within larger aggregate systems. This work presents a thermodynamic formalism for ranking CRN pathways under fixed throughput currents (fixed velocities of species flowing in and out of the system), where pathways represent subnetworks capable of performing the stipulated chemical conversion. We define a …
