# almost development closedness (van Oostrom 1997)

Consider the left-linear TRS R:

  h(f(f(c())),b()) -> f(h(h(h(c(),h(f(h(c(),f(b()))),a())),b()),c()))
  c() -> c()
  f(f(h(h(f(a()),a()),c()))) -> f(h(f(c()),b()))
  h(f(h(f(b()),h(h(f(h(c(),f(c()))),b()),a()))),h(a(),c())) -> c()

R is left-linear and every critical pair is almost development closed
