Abstract: | Background Interaction graphs (signed directed graphs) provide an important qualitative modeling approach for Systems Biology. They enable
the analysis of causal relationships in cellular networks and can even be useful for predicting qualitative aspects of systems
dynamics. Fundamental issues in the analysis of interaction graphs are the enumeration of paths and cycles (feedback loops)
and the calculation of shortest positive/negative paths. These computational problems have been discussed only to a minor
extent in the context of Systems Biology and in particular the shortest signed paths problem requires algorithmic developments. |
