The given Problem was:
a -> 
a b -> b a c b a 
b -> a 
c c ->

A self-embedding rewrite structure for the given SRS is:
   b b c b --(9)-> b b c b (#2971)
   OC+OC at 2
      OC: b b c b --(8)-> b b a c b (#1400)
          OC+OC at 0
             OC: b --(1)-> a (#3)
                 Rule
             OC: a b c b --(7)-> b b a c b (#671)
                 OC+OC at 1
                    OC: a b c --(5)-> b a (#95)
                        OC+OC at 2
                           OC: a b --(4)-> b a c (#22)
                               OC+OC at 3
                                  OC: a b --(2)-> b a c b (#7)
                                      OC+OC at 4
                                         OC: a b --(1)-> b a c b a (#2)
                                             Rule
                                         OC: a --(1)->  (#1)
                                             Rule
                                  OC: b --(2)->  (#5)
                                      OC+OC at 0
                                         OC: b --(1)-> a (#3)
                                             Rule
                                         OC: a --(1)->  (#1)
                                             Rule
                           OC: c c --(1)->  (#4)
                               Rule
                    OC: a b --(2)-> b a c b (#7)
                        OC+OC at 4
                           OC: a b --(1)-> b a c b a (#2)
                               Rule
                           OC: a --(1)->  (#1)
                               Rule
      OC: a --(1)->  (#1)
          Rule
Hence, the SRS is non-terminating.
