We consider universal computability of the LCTRS with only rule scheme Calc: Signature: eval :: Int -> Int -> Int -> o Rules: eval(i, j, k) -> eval(j, i + 1, k - 1) | i <= 100 /\ j <= k The system is accessible function passing by a sort ordering that equates all sorts. We start by computing the initial DP problem D1 = (P1, R UNION R_?, i, c), where: P1. (1) eval#(i, j, k) => eval#(j, i + 1, k - 1) | i <= 100 /\ j <= k ***** We apply the Usable Rules Processor on D1 = (P1, R UNION R_?, i, c). We obtain 0 usable rules (out of 1 rules in the input problem). Processor output: { D2 = (P1, {}, i, c) }. ***** We apply the Usable rules with respect to HORPO Processor on D2 = (P1, {}, i, c). Constrained HORPO yields: eval#3(i, j, k) (>) eval#3(j, i + 1, k - 1) | i <= 100 /\ j <= k We do this using the following settings: * Disregarded arguments: eval#3 3 * Precedence and permutation: eval#3 { 1 2 } * Well-founded theory orderings: [>]_{Bool} = {(true,false)} [>]_{Int} = {(x,y) | x < 1000 /\ x < y } Processor output: { }.
