*** 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 * 11 variable(s) and 6 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 : 11 vars, 6 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 22 vars, 10(10==10) transitions and 7 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 main *** Results : * Invariants = start -----> {I=J, I=J__o, G=H, G=H__o, D=E, D=E__o, B=C, B=C__o, A=F, A=A__o} stop -----> {I>=1, A<=I, A=F, A=A__o, C=C__o, E=E__o, H=H__o, J=J__o} lbl31 -----> {A>I, I>=1, A=F, A=A__o, C=C__o, E=E__o, H=H__o, J=J__o} lbl13 -----> {A+1>I, G+1>=0, I>=2, G+2<=I, D+1=I, J=J__o, H=H__o, E=E__o, C=C__o, A=F, A=A__o} start0 -----> {I=I__o, H=H__o, G=G__o, F=F__o, E=E__o, D=D__o, C=C__o, B=B__o, A=A__o, J=J__o, K=K__o} ____start0 -----> {true} lbl43 -----> {G+1>=0, A>I, G+2<=I, A=F, A=A__o, C=C__o, E=E__o, H=H__o, J=J__o} * Remember that we have no bad region * Acceleration has been applied around 1 location(s) * Stats = { time=0.021000; iterations=5; descendings=0; } print result in fast++ Finished !
