A variational principle for computing nonequilibrium fluxes and potentials in genome-scale biochemical networks
Constraint-based modeling Flux balance analysis
2015/7/3
We derive a convex optimization problem on a steady-state nonequilibrium network of biochemical
reactions, with the property that energy conservation and the second law of thermodynamics both hold
