YES weighted path orer with linear polynomial on natural numbers: pos_A(x1) = x1 + 2 p_A(x1) = x1 false_A = 1 s_A(x1) = x1 + 4 true_A = 3 0_A = 0 precedence: true > false > 0 > s > p > pos status: pos: [1] p: [1] false: [] s: [1] true: [] 0: [] the condition pos(0()) ->> true() is unsatisfiable for all substitutions.
