Toy-model. The universe of metabolic reactions for a simple toy-model containing 12 metabolites including two extracellular substrates S1 and S2 and 14 reactions. A fluctuating environment is generated by shuttling between the two alternative substrates, S1 and S2. The objective function is to maximize the biomass production rate averaged over all environmental conditions
