Abstract

Temporal logics and model-checking techniques have proved successful to respectively express biological properties of complex bio-chemical systems, and automatically verify their satisfaction in both qualitative and quantitative models. In this paper, we propose a finite time horizon model-checking algorithm for the existential fragment of LTL with numerical constraints over the reals, with the ability to compute the range of values of the real variables occurring in a formula that makes it true in a model. We illustrate this approach for the analysis of biological data time series, provide a set of biologically relevant patterns of formulas, and evaluate them on models of the cell cycle control and MAPK signal transduction.
