Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   b(a(b(a(b(a(a(a(b(x1))))))))) -> a(a(b(a(a(a(b(a(b(a(b(a(b(x1)))))))))))))

Q is empty.

----------------------------------------

(1) Strip Symbols Proof (SOUND)
We were given the following TRS:

   b(a(b(a(b(a(a(a(b(x1))))))))) -> a(a(b(a(a(a(b(a(b(a(b(a(b(x1)))))))))))))

By stripping symbols from the only rule of the system, we obtained the following TRS [ENDRULLIS]: 

   b(a(b(a(b(a(a(a(x)))))))) -> a(a(b(a(a(a(b(a(b(a(b(a(x))))))))))))

----------------------------------------

(2)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   b(a(b(a(b(a(a(a(x)))))))) -> a(a(b(a(a(a(b(a(b(a(b(a(x))))))))))))

Q is empty.

----------------------------------------

(3) RFCMatchBoundsTRSProof (EQUIVALENT)
Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 1. This implies Q-termination of R.
The following rules were used to construct the certificate:

   b(a(b(a(b(a(a(a(x)))))))) -> a(a(b(a(a(a(b(a(b(a(b(a(x))))))))))))

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
226, 227, 261, 262, 263, 264, 265, 266, 267, 268, 269, 270, 271, 272, 273, 274, 275, 276, 277, 278, 279, 280, 281, 282

Node 226 is start node and node 227 is final node.

Those nodes are connected through the following edges:

* 226 to 261 labelled a_1(0)* 227 to 227 labelled #_1(0)* 261 to 262 labelled a_1(0)* 262 to 263 labelled b_1(0)* 263 to 264 labelled a_1(0)* 264 to 265 labelled a_1(0)* 265 to 266 labelled a_1(0)* 266 to 267 labelled b_1(0)* 266 to 272 labelled a_1(1)* 267 to 268 labelled a_1(0)* 268 to 269 labelled b_1(0)* 268 to 272 labelled a_1(1)* 269 to 270 labelled a_1(0)* 270 to 271 labelled b_1(0)* 270 to 272 labelled a_1(1)* 271 to 227 labelled a_1(0)* 272 to 273 labelled a_1(1)* 273 to 274 labelled b_1(1)* 274 to 275 labelled a_1(1)* 275 to 276 labelled a_1(1)* 276 to 277 labelled a_1(1)* 277 to 278 labelled b_1(1)* 277 to 272 labelled a_1(1)* 278 to 279 labelled a_1(1)* 279 to 280 labelled b_1(1)* 279 to 272 labelled a_1(1)* 280 to 281 labelled a_1(1)* 281 to 282 labelled b_1(1)* 281 to 272 labelled a_1(1)* 282 to 227 labelled a_1(1)
