app2(app2(min, x), app2(app2(cons, y), z)) -> app2(app2(app2(if, app2(app2(le, x), y)), app2(app2(min, x), z)), app2(app2(min, y), z))
app2(app2(del, x), nil) -> nil
app2(app2(del, x), app2(app2(cons, y), z)) -> app2(app2(app2(if, app2(app2(eq, x), y)), z), app2(app2(cons, y), app2(app2(del, x), z)))

The set Q consists of the following terms:

app2(app2(le, 0), x0)
app2(app2(le, app2(s, x0)), 0)
app2(app2(le, app2(s, x0)), app2(s, x1))
app2(app2(eq, 0), 0)
app2(app2(eq, 0), app2(s, x0))
app2(app2(eq, app2(s, x0)), 0)
app2(app2(eq, app2(s, x0)), app2(s, x1))
app2(app2(app2(if, true), x0), x1)
app2(app2(app2(if, false), x0), x1)
app2(minsort, nil)
app2(minsort, app2(app2(cons, x0), x1))
app2(app2(min, x0), nil)
app2(app2(min, x0), app2(app2(cons, x1), x2))
app2(app2(del, x0), nil)
app2(app2(del, x0), app2(app2(cons, x1), x2))

We have to consider all minimal (P,Q,R)-chains.
