1 String Reversal

Since only unary symbols occur, one can reverse all terms and obtains the TRS
0(1(0(x1))) → 4(2(4(2(3(2(2(3(3(2(x1)))))))))) (59)
0(4(0(0(0(x1))))) → 4(3(0(2(2(1(4(4(4(3(x1)))))))))) (60)

1.1 Rule Removal

Using the linear polynomial interpretation over the naturals
[0(x1)] = 1 · x1 + 5
[1(x1)] = 1 · x1
[4(x1)] = 1 · x1 + 2
[2(x1)] = 1 · x1
[3(x1)] = 1 · x1
[5(x1)] = 1 · x1 + 3
all of the following rules can be deleted.
