*** 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 * 5 variable(s) and 9 locs(s) and 17 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 : 5 vars, 9 locations, 13 transitions * The initial state has label evalEx1start and the associated polyhedron is { $>=0,1>0} * There is/are 0 bad node(s) * Precomputing special stuff for ranking option 10 vars, 14(14==14) transitions and 10 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 main *** Results : * Invariants = evalEx1start -----> {C=C__o, B=B__o, A=A__o, D=D__o, E=E__o} evalEx1entryin -----> {B=B__o, A=A__o, D=D__o, C=C__o} evalEx1bb6in -----> {B<=A__o} evalEx1bbin -----> {B<=A__o, A {A>=B, B<=A__o} evalEx1bb4in -----> {C=D} evalEx1bb1in -----> {B>=D, C {A+1<=C, C=D, C>=D} evalEx1stop -----> {A>=B, B<=A__o} ____evalEx1start -----> {true} * Remember that we have no bad region * No accel has been applied * Stats = { time=0.011000; iterations=6; descendings=0; } print result in fast++ Finished !
