  • BIOCHAM 3.7 is a previous version of the Biochemical Abstract Machine software for modelilng and analysing biochemical reaction networks. BIOCHAM-web allows you to try it on-line through a web service. Beyond making simulations of different kinds, BIOCHAM provides unique features for
    • importing and exporting biochemical reaction networks (CRNs) s in different formalisms and formats,
    • performing various static analyses of CRNs,
    • specifying behaviors in (quantitative) temporal logic,
    • verifying tempoal properties by model-checking, and estimating parameter sensitivity and robustness,
    • searching parameter values under temporal logic constraints.
  • FO-CTL is a constraint solver for full First-Order Computation Tree Logic with linear arithmetic over the reals, FO-CTL(ℝlin), in Constrained Transition Systems.

  • ClpZinc a Horn clause front-end for the MiniZInc modelling language for expressing search strategies by constraints

  • MiniZinc-CMAES a stochastic optimization backend for the MiniZinc modelling language

  • Rules2CP a general purpose rule-based modelling language for constraint solving.
