Dependency Pair Analysis



R contains the following Dependency Pairs:

ACTIVE(g(X)) -> H(X)
ACTIVE(h(d)) -> G(c)
PROPER(g(X)) -> G(proper(X))
PROPER(g(X)) -> PROPER(X)
PROPER(h(X)) -> H(proper(X))
PROPER(h(X)) -> PROPER(X)
G(ok(X)) -> G(X)
H(ok(X)) -> H(X)
TOP(mark(X)) -> TOP(proper(X))
TOP(mark(X)) -> PROPER(X)
TOP(ok(X)) -> TOP(active(X))
TOP(ok(X)) -> ACTIVE(X)

Furthermore, R contains four SCCs.

On this DP problem, a Forward Instantiation SCC transformation can be performed.
As a result of transforming the rule

G(ok(X)) -> G(X)
one new Dependency Pair is created:

G(ok(ok(X''))) -> G(ok(X''))

The transformation is resulting in one new DP problem:

g(ok(X)) -> ok(g(X))
h(ok(X)) -> ok(h(X))
top(mark(X)) -> top(proper(X))
top(ok(X)) -> top(active(X))


Strategy:

innermost




The following dependency pairs can be strictly oriented:

TOP(ok(g(h(X'''')))) -> TOP(mark(h(h(X''''))))
TOP(ok(g(g(X'''')))) -> TOP(mark(h(g(X''''))))


Additionally, the following usable rules for innermost w.r.t. to the implicit AFS can be oriented:

h(ok(X)) -> ok(h(X))
g(ok(X)) -> ok(g(X))


Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(proper(x1))=  0  
  POL(c)=  0  
  POL(g(x1))=  1  
  POL(d)=  0  
  POL(h(x1))=  0  
  POL(mark(x1))=  x1  
  POL(ok(x1))=  x1  
  POL(TOP(x1))=  x1  

resulting in one new DP problem.

On this DP problem, a Forward Instantiation SCC transformation can be performed.
As a result of transforming the rule

TOP(mark(g(g(X')))) -> TOP(g(g(proper(X'))))
no new Dependency Pairs are created.
The transformation is resulting in one new DP problem:
