*** 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 * 7 variable(s) and 12 locs(s) and 15 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 : 7 vars, 12 locations, 15 transitions * The initial state has label evalfstart and the associated polyhedron is { $>=0,1>0} * There is/are 0 bad node(s) * Precomputing special stuff for ranking option 14 vars, 16(16==16) transitions and 13 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 main *** Results : * Invariants = evalfstart -----> {E=E__o, D=D__o, C=C__o, B=B__o, A=A__o, F=F__o, G=G__o} evalfentryin -----> {E=E__o, D=D__o, C=C__o, B=B__o, A=A__o, F=F__o, G=G__o} evalfbb10in -----> {D<=A__o, A=B__o, B=C__o, C=D__o} evalfbb8in -----> {E>=1, D>0, D<=A__o, A=B__o, B=C__o, C=D__o} evalfreturnin -----> {D<=0, D<=A__o, A=B__o, B=C__o, C=D__o} evalfbb6in -----> {D<=F, E>=1, D>0, A>=E, D<=A__o, A=B__o, B=C__o, C=D__o} evalfbb9in -----> {E>=1, D<=A__o, A0, A=B__o, B=C__o, C=D__o} evalfbb4in -----> {D<=F, E>=1, D>0, C>=G, B>=F, A>=E, D<=A__o, A=B__o, B=C__o, C=D__o} evalfbb7in -----> {E>=1, D<=F, D<=A__o, A>=E, B0, A=B__o, B=C__o, C=D__o} evalfbb3in -----> {E>=1, D<=F, C>=G, D<=A__o, A>=E, B>=F, D>0, E>=G, A=B__o, B=C__o, C=D__o} evalfbb5in -----> {E>=1, D<=F, C>=G, D<=A__o, A>=E, B>=F, D>0, E {D<=0, D<=A__o, A=B__o, B=C__o, C=D__o} ____evalfstart -----> {true} * Remember that we have no bad region * No accel has been applied * Stats = { time=0.021000; iterations=6; descendings=0; } print result in fast++ Finished !
