*** 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 3 locs(s) and 4 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, 3 locations, 4 transitions * The initial state has label f0 and the associated polyhedron is { $>=0,1>0} * There is/are 0 bad node(s) * Precomputing special stuff for ranking option 24 vars, 5(5==5) transitions and 4 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 mainjust one = {E=E__o,A=K__o,F=F__o,B=0,C=1,D=0,G=G__o,H=H__o,I=I__o, J=J__o,$>=0,1>0}just one = {E=E__o,A=K__o,F=F__o,B=1,C=1, D=1,G=G__o,H=H__o,I=I__o, J=J__o,$>=0,1>0}just one = { E=E__o,A=K__o,F=F__o,B=1,J=J__o,D=1,G=G__o,H=H__o,I=I__o,C>=1,$>=0,C<=32,1>0}just one = { E=E__o,A=K__o,F=F__o,J=J__o,B+1=C,D=0,G=G__o,H=H__o,I=I__o,B>=0,$>=0,B<=31, 1>0}just one = {E=E__o,A=K__o,F=F__o,I=I__o,J=J__o,D=0,G=G__o,H=H__o,C<=32, B+1<=C,$>=0,B>=0,1>0}just one = {E=E__o,A=K__o,F=F__o, I=I__o,J=J__o,D=1,G=G__o, H=H__o,B<=C,C<=32,$>=0, B>=1,1>0}just one = { E=E__o,A=K__o,F=F__o,I=I__o,J=J__o,D=0,G=G__o,H=H__o,C<=32,B+1<=C,$>=0,B>=0, 1>0}just one = {E=E__o,A=K__o,F=F__o,I=I__o,J=J__o,D=1,G=G__o,H=H__o,B<=C, C<=32,$>=0,B>=1,1>0} *** Results : * Invariants = f0 -----> {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} f28 -----> {C<=32, C>31, B<=C, B>=0, B=E, B=F, H=J, A=K__o, H=I} ____f0 -----> {true} f5 -----> {B>=0, C<=32, B<=C, J=J__o, I=I__o, H=H__o, G=G__o, F=F__o, E=E__o, A=K__o} * Remember that we have no bad region * Acceleration has been applied around 1 location(s) * Stats = { time=0.018000; iterations=4; descendings=0; } print result in fast++ Finished !
