*** 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 * 8 variable(s) and 7 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 : 8 vars, 7 locations, 12 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 16 vars, 13(13==13) transitions and 8 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 mainjust one = empty(16)just one = empty(16)just one = empty(16)just one = empty(16) *** Results : * Invariants = start -----> {G=H, G=H__o, E=F, E=F__o, B=C, B=C__o, A=D, A=A__o} stop -----> {F=F__o, H=H__o, A=A__o, B=C__o, A=D, B=C} lbl6 -----> {A>0, A>=B, G=H, G=H__o, E=F, E=F__o, B=C, B=C__o, A=D, A=A__o} cut -----> {A>1, A {F=F__o, E=E__o, D=D__o, C=C__o, B=B__o, A=A__o, G=G__o, H=H__o} ____start0 -----> {true} lbl121 -----> {G>=0, A+1>E, B>G, E>=1, A {A+B>G+1, A>=1, G>=1, AG, B=C, A=D, E=0, A=A__o, B=C__o, F=F__o, H=H__o} * Remember that we have no bad region * Acceleration has been applied around 2 location(s) * Stats = { time=0.013000; iterations=5; descendings=0; } print result in fast++ Finished !
