YES weighted path orer with linear polynomial on natural numbers: add_A(x1,x2) = x1 + x2 + 2 s_A(x1) = 1 0_A = 1 gcd_A(x1,x2) = x1 + x2 + 1 leq_A(x1,x2) = 1 false_A = 2 precedence: leq > add > gcd > 0 > false > s status: add: [1,2] s: [] 0: [] gcd: [] leq: [] false: [] the condition leq(x2,0()) ->> false() is unsatisfiable for all substitutions.
