(3) RFCMatchBoundsTRSProof (EQUIVALENT transformation)
Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 4. This implies Q-termination of R.
The following rules were used to construct the certificate:
f(f(active(X))) → f(g(f(c(mark(X)))))
c(active(X)) → d(mark(X))
h(active(X)) → d(c(mark(X)))
f(active(X)) → active(f(X))
h(active(X)) → active(h(X))
mark(f(X)) → f(mark(X))
mark(h(X)) → h(mark(X))
f(proper(X)) → proper(f(X))
c(proper(X)) → proper(c(X))
g(proper(X)) → proper(g(X))
d(proper(X)) → proper(d(X))
h(proper(X)) → proper(h(X))
ok(f(X)) → f(ok(X))
ok(c(X)) → c(ok(X))
ok(g(X)) → g(ok(X))
ok(d(X)) → d(ok(X))
ok(h(X)) → h(ok(X))
mark(top(X)) → proper(top(X))
ok(top(X)) → active(top(X))
The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
1, 4, 10, 11, 12, 13, 14, 22, 24, 25, 26, 27, 28, 29, 32, 34, 35, 36, 37, 38, 39, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 64, 65, 66, 67, 71, 72, 73, 75, 78, 80, 84, 85, 86, 87, 91
Node 1 is start node and node 4 is final node.
Those nodes are connected through the following edges:
