*** 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 3 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, 3 locations, 9 transitions * The initial state has label f2 and the associated polyhedron is { $>=0,1>0} * There is/are 0 bad node(s) * Precomputing special stuff for ranking option 12 vars, 10(10==10) transitions and 4 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 mainjust one = {A=A__o,C=0,D=D__o,B=B__o,$>=0,A0}just one = { A=A__o,C=0,D=D__o,B=B__o,$>=0,A0}just one = {D=D__o,C=0,B>=B__o,A=0,A+B__o>=B+A__o, 1>0,A+B__o<=B+A__o+1}just one = { D=D__o,C=0,B>=B__o,A=0,A+B__o>=B+A__o,1>0,A+B__o<=B+A__o+1}just one = { B=B__o,C=0,D=D__o,A>=A__o,$>=0,A0}just one = {B=B__o,C=0,D=D__o, A>=A__o,$>=0,A0}just one = { D=D__o,C=0,A+B__o>=B+A__o,B>=B__o,$>=0,A0}just one = {D=D__o,C=0, A+B__o>=B+A__o, B>=B__o,$>=0,A0} *** Results : * Invariants = f2 -----> {D=D__o, C=C__o, B=B__o, A=A__o, E=E__o, F=F__o} f300 -----> {B>=B__o, A+B__o>=B+A__o, A>B} ____f2 -----> {true} f1 -----> {A+B__o>=B+A__o, B>=B__o, D=D__o} * Remember that we have no bad region * Acceleration has been applied around 1 location(s) * Stats = { time=0.029000; iterations=4; descendings=0; } print result in fast++ Finished !
