The analysis of complex chemical reaction systems is frequently complicatedbecause of the coexistence of fast cyclic reaction sequences and slower pathways that yield a net production or destruction of a certain species of interest.An algorithm for the determination of both these types of reaction sequences (in a given reaction system) is presented. Under the assumption that reaction rates are known, it finds the mostimportant pathways by solving a linear optimization problem for each of them.This algorithm may be used as a tool for the interpretation of chemical model runs.For illustration, it is applied to examples in stratospheric chemistry, including the determination of catalytic ozone destruction cycles.
