*** 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 * 11 variable(s) and 10 locs(s) and 23 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 : 11 vars, 10 locations, 23 transitions * The initial state has label start and the associated polyhedron is { $>=0,1>0} * There is/are 0 bad node(s) * Precomputing special stuff for ranking option 22 vars, 24(24==24) transitions and 11 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 mainjust one = {A=A__o,B=B__o,H=0,1>0,A>B__o,AD+E__o,E>=E__o,$>=0, A+1>=D}just one = {H=0,A=A__o,E>=E__o,1>0,B>=B__o,A+1>=D, A>B,A=0}just one = {H=0,A=A__o, E>=E__o,1>0, B>=B__o, A+1>=D,A>B, A=0}just one = { H=0,A=A__o,E>=E__o,1>0,B>=B__o,A+1>=D,A>B,A=0} *** Results : * Invariants = f0 -----> {B>=B__o, E>=E__o, A=A__o} f35 -----> {A+E>D+E__o, A>=D, A>B, B>=B__o, E>=E__o, A {A<=B, B>=B__o, E>=E__o, A=A__o} start -----> {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, J=J__o, K=K__o} ____start -----> {true} f12 -----> {E>=E__o, B>=B__o, A>B, A>=D, A+E>D+E__o, A=A__o} f22 -----> {2A+2E>B+D+2E__o, A+E>D+E__o, A>=D, A>B, B>=B__o, E>=E__o, A {2A+2E>B+D+2E__o, A+E>D+E__o, A>=D, A>B, B>=B__o, E>=E__o, A {E>=E__o, B>=B__o, A>B, A+1>=D, A {E>=E__o, B>=B__o, A>B, A>=D, A {E>=E__o, B>=B__o, A>B, A>=D, A
