*** 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 * 9 variable(s) and 13 locs(s) and 21 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 : 9 vars, 13 locations, 21 transitions * The initial state has label evalNestedLoopstart and the associated polyhedron is { $>=0,1>0} * There is/are 0 bad node(s) * Precomputing special stuff for ranking option 18 vars, 22(22==22) transitions and 14 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 main *** Results : * Invariants = evalNestedLoopstart -----> {G=G__o, F=F__o, E=E__o, D=D__o, C=C__o, B=B__o, A=A__o, H=H__o, I=I__o} evalNestedLoopentryin -----> {H=H__o, G=G__o, F=F__o, E=E__o, D=D__o, C=C__o, B=B__o, A=A__o} evalNestedLoopbb9in -----> {D>=0, C>=0, B>=0, A>=0, A=A__o, B=B__o, C=C__o} evalNestedLoopreturnin -----> {A>=0, D>=0, C>=0, B>=0, A=A__o, B=B__o, C=C__o} evalNestedLoopbb10in -----> {A>D, B>=0, C>=0, D>=0, C=C__o, B=B__o, A=A__o} evalNestedLoopbb6in -----> {B>=0, A>D, D<=F, D>=0, C>=0, B+1>E, A=A__o, B=B__o, C=C__o} evalNestedLoopbb8in -----> {B+1>E, D<=F, B>=0, D>=0, A>D, C>=0, A=A__o, B=B__o, C=C__o} evalNestedLoopbb7in -----> {A>D, B>=0, B>E, C>=0, D>=0, D<=F, C=C__o, B=B__o, A=A__o} evalNestedLoopbb1in -----> {B>=0, D<=F, B>E, D>=0, C>=0, A>D, A=A__o, B=B__o, C=C__o} evalNestedLoopbb3in -----> {B>E, B>=0, A>D, D<=F, F<=H, D>=0, C>=0, C+F+1>H, E+1=G, A=A__o, B=B__o, C=C__o} evalNestedLoopbb4in -----> {A>D, B>=0, B>E, C>H, D>=0, F<=H, D<=F, E+1=G, C=C__o, B=B__o, A=A__o} evalNestedLoopbb2in -----> {B>=0, D<=F, B>E, D>=0, F<=H, C>H, A>D, E+1=G, A=A__o, B=B__o, C=C__o} evalNestedLoopstop -----> {A>=0, D>=0, C>=0, B>=0, A=A__o, B=B__o, C=C__o} ____evalNestedLoopstart -----> {true} * Remember that we have no bad region * No accel has been applied * Stats = { time=0.044000; iterations=6; descendings=0; } print result in fast++ Finished !
