The following weak DPs constitute a sub-graph of the DG that is closed under successors. The DPs are removed.
1: weight#(cons(n,cons(m,x))) -> c_4(weight#(sum(cons(n,cons(m,x)),cons(0(),x))))
*** Step 5.b:3.b:2: EmptyProcessor WORST_CASE(?,O(1))
+ Considered Problem:
- Weak TRS:
sum(cons(0(),x),y) -> sum(x,y)
sum(cons(s(n),x),cons(m,y)) -> sum(cons(n,x),cons(s(m),y))
sum(nil(),y) -> y
- Signature:
{sum/2,weight/1,sum#/2,weight#/1} / {0/0,cons/2,nil/0,s/1,c_1/1,c_2/1,c_3/0,c_4/1,c_5/0}
- Obligation:
innermost runtime complexity wrt. defined symbols {sum#,weight#} and constructors {0,cons,nil,s}
+ Applied Processor:
EmptyProcessor
+ Details:
The problem is already closed. The intended complexity is O(1).
