    Graph theory assumes that cost alone governs connected traversal; if node A is connected to node C, then it is always possible to traverse the graph from A to C, provided the cost is paid. Meanwhile, chemically, a reaction must obey its stoichiometry ( i.e. all reactants must be present for a reaction to occur), and there must be a non-negative ...
