Software development

  • BIOCHAM (the Biochemical Abstract Machine) is a software environment for modeling, analyzing and synthesizing biochemical interaction systems. 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 models in different formalisms and formats,
    • performing various static analyses,
    • specifying behaviors in (quantitative) temporal logic,
    • model-checking and robustness computation,
    • searching parameter values with temporal logic constraints.
    • compiling behaviour specifications and mixed analog-digital programs in elementary reactions (this is in Biocham v4 alpha a complete rewriting of Biocham, not released yet).

  • CellStar image tracker as part of the Yeast Image Toolkit a collective effort for automatic tracking of yeast cells in time-lapse microscopy.

  • 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
