*** 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 * 12 variable(s) and 6 locs(s) and 17 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 : 12 vars, 6 locations, 17 transitions * The initial state has label start0 and the associated polyhedron is { $>=0,1>0} * There is/are 0 bad node(s) * Precomputing special stuff for ranking option 24 vars, 18(18==18) transitions and 7 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 mainjust one = {F=G__o,L=A__o,A=A__o,B=C__o,B=C,D=0,E=0,K=K__o,F=G,H=0, E__o=0,J=2,I=I__o,A__o>=0,1>0,$>=0,B>1}just one = { I=I__o,L=A__o,A=A__o,G=G__o,B=C,D=0,E=0,B=C__o,K=K__o,H=0,E__o=0,J=2,A__o>=0, 1>0,$>=0,B>1}just one = {L=A__o,I=I__o,A=L,G=G__o,B=C,D=0,E=0,B=C__o,K=K__o, H=0,E__o=0,L>=0,1>0,$>=0,J>=2,B+1>J}just one = { L=A__o,I=I__o,A=L,G=G__o,B=C,D=0,E=0,B=C__o,K=K__o,H=0,E__o=0,L>=0,1>0,$>=0, J>=2,B+1>J} *** Results : * Invariants = start -----> {J=K, J=K__o, H=I, H=I__o, F=G, F=G__o, D=E, D=E__o, B=C, B=C__o, A=L, A=A__o} stop -----> {I=I__o, K=K__o, A=L, A=A__o, B=C__o, D=E__o, G=G__o, D=E, B=C} start0 -----> {J=J__o, 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, K=K__o, L=L__o} ____start0 -----> {true} lbl131 -----> {D>=0, A>=0, J>=1, B>0, A+B+1>J, B=C, D=E, D=H, A=L, A=A__o, B=C__o, D=E__o, G=G__o, I=I__o, K=K__o} lbl121 -----> {A<=F, A+B>F, H>=1, D+1>H, A>=0, B=C, D=E, F=J, A=L, A=A__o, B=C__o, D=E__o, G=G__o, I=I__o, K=K__o} lbl111 -----> {A+1>F, J>=0, F>=J+1, D>0, B>J, B=C, D=E, H=1, A=L, A=A__o, B=C__o, D=E__o, G=G__o, I=I__o, K=K__o} * Remember that we have no bad region * Acceleration has been applied around 3 location(s) * Stats = { time=0.046000; iterations=5; descendings=0; } print result in fast++ Finished !
