*** 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 * 4 variable(s) and 9 locs(s) and 12 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 : 4 vars, 9 locations, 12 transitions * The initial state has label evalrsdstart and the associated polyhedron is { $>=0,1>0} * There is/are 0 bad node(s) * Precomputing special stuff for ranking option 8 vars, 13(13==13) transitions and 10 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 main *** Results : * Invariants = evalrsdstart -----> {B=B__o, A=A__o, C=C__o, D=D__o} evalrsdentryin -----> {C=C__o, B=B__o, A=A__o} evalrsdbbin -----> {A>=0, A=A__o, B=B__o, C=C__o} evalrsdreturnin -----> {A=A__o} evalrsdbb4in -----> {2A>=B, A>=0, B>=C, A=A__o} evalrsdbb1in -----> {2A>=B, B>=C, A<=C, A=A__o} evalrsdbb2in -----> {B>=C, 2A>=B, A<=C, A=A__o} evalrsdbb3in -----> {B>=C, 2A>=B, A<=C, A=A__o} evalrsdstop -----> {A=A__o} ____evalrsdstart -----> {true} * Remember that we have no bad region * No accel has been applied * Stats = { time=0.005000; iterations=5; descendings=0; } print result in fast++ Finished !
