*** 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 * 10 variable(s) and 14 locs(s) and 27 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 : 10 vars, 14 locations, 27 transitions * The initial state has label f2 and the associated polyhedron is { $>=0,1>0} * There is/are 0 bad node(s) * Precomputing special stuff for ranking option 20 vars, 28(28==28) transitions and 15 locs now * Printing option = Infile+Invars * Parsing OK, now analysing * LRA with acceleration with delay = 1 main *** Results : * Invariants = f4 -----> {A0, G__o>0, E+1>0, C+1>E, A+1>0} f14 -----> {A+H__o<=C+G__o, 2A+1<=E+2G__o, A0, G__o>0, E+1>0, C+1>E, A+1>0} f13 -----> {A+1>0, C>=E, E+1>0, H__o>0, A+H__o<=E+G__o, A+1<=G__o, A=B} f400 -----> {false} f2 -----> {J=J__o, 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} f23 -----> {G__o>0, H__o>0, A=G__o, B=I__o, C=H__o, E=1, D=J__o} f33 -----> {A+1>0, C>=E, E+2>0, H__o>0, A+H__o+1<=E+G__o, A+1<=G__o} f6 -----> {A+1>0, C>=E, E+2>0, H__o>0, A+H__o+1<=E+G__o, A+1<=G__o} f43 -----> {A+1>0, C>=E, E+2>0, H__o>0, E<=0, A+H__o+1<=E+G__o} f53 -----> {A+1>0, C>=E, E+1>0, H__o>0, A+H__o<=E+G__o, A+1<=G__o} f61 -----> {B+1>0, E+1>0, H__o>0, B+H__o<=E+G__o, B+1<=G__o, A=B, C=E} f63 -----> {A+1>0, C>=E, E+1>0, H__o>0, A+H__o<=E+G__o, A+1<=G__o, A=B} f71 -----> {B+1>0, E+1>0, H__o>0, B+H__o<=E+G__o, B+1<=G__o, A=B, C=E} f73 -----> {A+1>0, C>=E, E+1>0, H__o>0, A+H__o<=E+G__o, A+1<=G__o, A=B} ____f2 -----> {true} * Remember that we have no bad region * No accel has been applied * Stats = { time=0.092000; iterations=5; descendings=0; } print result in fast++ Finished !
