The rewrite relation of the following TRS is considered.

Begin(c(x0)) | → | Wait(Right2(x0)) |
Right1(a(End(x0))) | → | Left(c(b(c(b(a(End(x0))))))) |
Right2(c(End(x0))) | → | Left(End(x0)) |
Right1(a(x0)) | → | Aa(Right1(x0)) |
Right2(a(x0)) | → | Aa(Right2(x0)) |
Right1(b(x0)) | → | Ab(Right1(x0)) |
Right2(b(x0)) | → | Ab(Right2(x0)) |
Right1(c(x0)) | → | Ac(Right1(x0)) |
Right2(c(x0)) | → | Ac(Right2(x0)) |
