We use the technique of [LOPSTR]. With regard to the inferred argument filtering the predicates were used in the following modes:
perm1_in: (b,f)
app210_in: (f,f,f,b)
app120_in: (b,b,b,f)
app125_in: (b,b,f)
perm21_in: (b,f)
app240_in: (f,f,f,b)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

APP240_IN_AAAG(.(X294, T130)) → APP240_IN_AAAG(T130)
The graph contains the following edges 1 > 1
