*** 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 * 6 variable(s) and 5 locs(s) and 9 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 : 6 vars, 5 locations, 9 transitions * The initial state has label start0 and the associated polyhedron is { $>=0,1>0} * There is/are 0 bad node(s) * Precomputing special stuff for ranking option 12 vars, 10(10==10) transitions and 6 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 mainjust one = empty(12)just one = empty(12)just one = empty(12)just one = empty(12) *** Results : * Invariants = start -----> {E=F, E=F__o, C=D, C=D__o, A=B, A=A__o} stop -----> {C<=E, C+1>=E, A<=C+1, E>=1, A=B, A=A__o, D=D__o, F=F__o} start0 -----> {D=D__o, C=C__o, B=B__o, A=A__o, E=E__o, F=F__o} ____start0 -----> {true} lbl71 -----> {E>=0, C>=1, A>C, A>E+1, A=B, A=A__o, D=D__o, F=F__o} cut -----> {E>=1, A>E+1, A=B, A=C+1, A=A__o, D=D__o, F=F__o} * Remember that we have no bad region * Acceleration has been applied around 2 location(s) * Stats = { time=0.006000; iterations=5; descendings=0; } print result in fast++ Finished !
