1. optStoic

• An MINLP-based optimization procedure for identifying the optimal stoichiometry of a reaction subject to thermodynamic constraints, charge and elemental balance.

2. minFlux or minRxn

• An MILP procedure to identify pathway(s) that carry minimal flux or consist of minimal number of reaction that conform to the given reaction stoichiometry.

The reaction and metabolite IDs are derived from the KEGG database (http://www.genome.jp/kegg/).
