Example of modularization problem. (A) Network representation. (Box-shaped vertices) Species; (diamond-shaped vertices) reactions. Low-confidence reaction vertices are marked by two borders. (B) Reduced ordered multiple-valued decision diagram depicting the choices of species to measure in the example network to obtain an insulating modularization (IM). Conveniently, only decisions leading either to a strict or a simple modularization are shown. All graphs were drawn with GRAPHVIZ (43).
