*** 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 * 5 variable(s) and 11 locs(s) and 14 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 : 5 vars, 11 locations, 14 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 10 vars, 15(15==15) transitions and 12 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 main *** Results : * Invariants = evalfstart -----> {C=C__o, B=B__o, A=A__o, D=D__o, E=E__o} evalfentryin -----> {C=C__o, B=B__o, A=A__o, D=D__o, E=E__o} evalfbb10in -----> {A>=1, B=B__o} evalfbb8in -----> {C>=1, A>=1, A<=B, B=B__o} evalfreturnin -----> {A>B, A>=1, B=B__o} evalfbb6in -----> {C>=1, B+1>=D, A>=C, A+1<=D, B=B__o} evalfbb4in -----> {E>=1, C>=1, B>=D, A>=C, A+1<=D, B=B__o} evalfbb7in -----> {A+1<=D, A>=C, B+1>=D, C>=1, B {D>=E, E>=1, C>=1, B>=D, A>=C, A+1<=D, B=B__o} evalfbb5in -----> {D=1, B>=D, A>=C, A+1<=D, B=B__o} evalfstop -----> {A>B, A>=1, B=B__o} ____evalfstart -----> {true} * Remember that we have no bad region * No accel has been applied * Stats = { time=0.017000; iterations=8; descendings=0; } print result in fast++ Finished !
