*** Aspic by Laure Gonnord, version 3.4 Binary compiled on vendredi 1 janvier 2016 Input file = main.fst *** 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 8 locs(s) and 12 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, 8 locations, 12 transitions * The initial state has label evalwisestart and the associated polyhedron is { $>=0,1>0} * There is/are 0 bad node(s) * Precomputing special stuff for ranking option 4 vars, 13(13==13) transitions and 9 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 main *** Results : * Invariants = evalwisestart -----> {A=A__o, B=B__o} evalwiseentryin -----> {B=B__o, A=A__o} evalwisereturnin -----> {B+2>=B__o, A+2>=A__o, A+B>=A__o+B__o} evalwisebb6in -----> {A<=A__o+B__o, B<=A__o+B__o, B>=A__o, A>=B__o} evalwisebb3in -----> {A>=B__o, B>=A__o, B<=A__o+B__o, A<=A__o+B__o, A+B+2<2A__o+2B__o} evalwisebb4in -----> {A>=B__o, A>B, A<=A__o+B__o, A+B+2<2A__o+2B__o, B>=A__o} evalwisebb5in -----> {A>=B__o, B<=A__o+B__o, A+B+2<2A__o+2B__o, A<=B, B>=A__o} evalwisestop -----> {B+2>=B__o, A+2>=A__o, A+B>=A__o+B__o} ____evalwisestart -----> {true} * Remember that we have no bad region * No accel has been applied * Stats = { time=0.005000; iterations=5; descendings=0; } print result in fast++ Finished !
