  1. a Filtered network (see text). The MILP approach (sasita) and the combinatorial one (combi) are applied to several metabolic networks. For each instance, we provide the size of the network (number of compounds and reactions), the number of source and target compounds, and the time spent by both approaches (\(t_{sasita},\ t_{Combi}\)). One asterisk means that the combinatorial approach could not finish within the time limit
