   * ANALYSIS 
    * with acceleration 
   * delay of widening = 1 
   * steps of descending sequence = 0

   * Name of model = main, Name of file = main.fst 
   * 4 variable(s) and 10 locs(s) and 16 transitions(s) in the .fst
   * Searching objective in fast strategy 
       -> we suppose that we want to compute post*(init) with init a convex set
       or post*(init) and bad if the state bad exists and bad is convex
       -> Initial region "init" found
       -> Finding initial polyhedron. OK. 
       -> No bad region
INFO : 4 vars, 10 locations, 16 transitions 
   * The initial state has label evalperfectstart and the associated polyhedron is {
$>=0,1>0} 
   * There is/are 0 bad node(s)
   * Precomputing special stuff for ranking option
 8 vars, 17(17==17) transitions and 11 locs now 
  * Printing option = Infile+Invars 
   * Parsing OK, now analysing 
   * LRA with acceleration with delay =  1
