Found a loop by semiunifying a rule from P directly.

The TRS P consists of the following rules:

ROW2COL_IN_AAAGA(.([], .([], z0))) → ROW2COL_IN_AAAGA(.([], .([], .([], z0))))

The TRS R consists of the following rules:none

s = ROW2COL_IN_AAAGA(.([], .([], z0))) evaluates to t =ROW2COL_IN_AAAGA(.([], .([], .([], z0))))

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:

Semiunifier: [ ]
Matcher: [z0 / .([], z0)]

Rewriting sequence

The DP semiunifies directly so there is only one rewrite step from ROW2COL_IN_AAAGA(.([], .([], z0))) to ROW2COL_IN_AAAGA(.([], .([], .([], z0)))).

Q DP problem:
The TRS P consists of the following rules:

Rewriting sequence

The DP semiunifies directly so there is only one rewrite step from ROW2COL_IN_AAAGA(.([], .([], z0))) to ROW2COL_IN_AAAGA(.([], .([], .([], z0)))).
