 Configuration of Aspic * (version 3.4) 
   * name of file : main.fst 
   * inputfile of type (real) Fast format 
   * PRINTING all stuff for compsys ranking method 
   * DEBUG : Only prints analysis steps in a separate .log file 
   * PRINTING STUFF : Infile+Invars 
   * ANALYSIS 
    * with acceleration 
   * delay of widening = 1 
   * steps of descending sequence = 0 
   * newpath heuristic = disabled 
   * Name of model = main, Name of file = main.fst 
   * 2 variable(s) and 3 locs(s) and 3 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 : 2 vars, 3 locations, 3 transitions 
   * The initial state has label l0 and the associated polyhedron is {
$>=0,1>0} 
   * There is/are 0 bad node(s)
   * Precomputing special stuff for ranking option
 4 vars, 4(4==4) transitions and 4 locs now 
  * Printing option = Infile+Invars 
   * Parsing OK, now analysing 
   * LRA with acceleration with delay =  1 
main
*** Results : 
   *  Invariants =  
l0 -----> {A=A__o, B=B__o} 

l2 -----> {B<=0, A>=0, A+B=B__o} 

____l0 -----> {true} 

l1  -----> {B<=B__o, A+B=B__o} 
    * Remember that we have no bad region 
   * Acceleration has been applied around 1 location(s)
   * Stats =  { time=0.000000; iterations=1; descendings=0; }
