*** 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 5 locs(s) and 10 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, 5 locations, 10 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, 11(11==11) transitions and 6 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 main *** Results : * Invariants = start -----> {F=G, F=G__o, D=E, D=E__o, B=C, B=C__o, A=H, A=A__o} stop -----> {A<=H, H>4, A=A__o, C=C__o, E=E__o, G=G__o} start0 -----> {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} lbl92 -----> {A<=D, 5D<=F+10, F>=0, F<=10, D+1=H, A=A__o, C=C__o, E=E__o, G=G__o} lbl82 -----> {B>=0, H>2, H<=4, B<=9, A<=H, G=G__o, E=E__o, C=C__o, B+1=F, A=A__o} * Remember that we have no bad region * Acceleration has been applied around 2 location(s) * Stats = { time=0.011000; iterations=4; descendings=0; } print result in fast++ Finished !
