DFBAlab simulation results of example 2. Two cyclic steady states are presented. Simulation 1 (solid line) was performed with lexicographic objectives presented in Table 2, whereas simulation 2 (dashed line) used the negative of Objective 4 for algae. Significant differences can be observed in the predicted concentrations of yeast, glucose, and oxygen. Computation times for simulations 1 and 2 where 82 and 74 seconds, respectively.
