Problem: f(g(x),g(x)) -> f(x,h(x,g(c()))) Proof: Church Rosser Transformation Processor (kb): f(g(x),g(x)) -> f(x,h(x,g(c()))) critical peaks: joinable Matrix Interpretation Processor: dim=1 interpretation: [h](x0, x1) = x0 + x1 + 1, [c] = 0, [f](x0, x1) = 2x0 + x1 + 4, [g](x0) = x0 + 1 orientation: f(g(x),g(x)) = 3x + 7 >= 3x + 6 = f(x,h(x,g(c()))) problem: Qed
