  - deep restructuration of the code (safer, simpler and more efficient)


  Compared to version 7.0, the new version provides with

    and graph theory, and formalizations of the ABR algorithm, CTL and
    TCTL temporal logic, the Railroad Crossing Problem, a subset of the
    C language, imperative Bresenham line drawing algorithm, imperative
    Marché's minimal edition distance algorithm, Buchberger's algorithm,
