(0) Obligation:

The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(1, n^1).


The TRS R consists of the following rules:

and(not(not(x)), y, not(z)) → and(y, band(x, z), x)

Rewrite Strategy: INNERMOST

(1) CpxTrsToCdtProof (BOTH BOUNDS(ID, ID) transformation)

Converted Cpx (relative) TRS to CDT

(3) CdtUsableRulesProof (EQUIVALENT transformation)

The following rules are not usable and were removed:

and(not(not(z0)), z1, not(z2)) → and(z1, band(z0, z2), z0)

(5) CdtRuleRemovalProof (UPPER BOUND(ADD(n^1)) transformation)

Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.

AND(not(not(z0)), z1, not(z2)) → c(AND(z1, band(z0, z2), z0))
We considered the (Usable) Rules:none
And the Tuples:

AND(not(not(z0)), z1, not(z2)) → c(AND(z1, band(z0, z2), z0))
The order we found is given by the following interpretation:
Polynomial interpretation :

POL(AND(x1, x2, x3)) = [3]x1 + [3]x2 + x3   
POL(band(x1, x2)) = [2]   
POL(c(x1)) = x1   
POL(not(x1)) = [3] + x1
