*** 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 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 : 5 vars, 5 locations, 9 transitions * The initial state has label f0 and the associated polyhedron is { $>=0,1>0} * There is/are 0 bad node(s) * Precomputing special stuff for ranking option 10 vars, 10(10==10) transitions and 6 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 mainjust one = {D=0,C+3=E__o,A+1=E__o,B=0,$>=0,E__o>2,1>0}just one = { D=0,A+B+1=E__o,A=C+2,$>=0,A>1,1>0,B>=0}just one = {D=0,A+B+1=E__o,A=C+2, $>=0,A>1,1>0,B>=0}just one = { D=0,C+1>0,A>=C+2,$>=0,A+B+2>=E__o,1>0,B+1>0,A+1<=E__o,A+B+1<=E__o}just one = { D=0,$>=0,C+1>0,A>=C+2,1>0,B+1>0,A+1<=E__o,A+B+1<=E__o}just one = {D=0,$>=0, C+1>0, A>=C+2, 1>0,B+1>0, A+1<=E__o, A+B+1<=E__o}just one = { D=0,$>=0,C+1>0,A>=C+2,1>0,B+1>0,A+1<=E__o,A+B+1<=E__o} *** Results : * Invariants = f0 -----> {C=C__o, B=B__o, A=A__o, D=D__o, E=E__o} f6 -----> {A<=B+E__o, B<=0, B+1>0} f10 -----> {A+B<=E__o, A+1<=E__o, B+1>0, A+1>0} f25 -----> {A<=0, A<=B+E__o, B<=0, B+1>0} ____f0 -----> {true} f14 -----> {A+B+1<=E__o, A+1<=E__o, C+2>0, B+1>0, A>=C+1} * Remember that we have no bad region * Acceleration has been applied around 1 location(s) * Stats = { time=0.017000; iterations=6; descendings=0; } print result in fast++ Finished !
