The system is accessible function passing by a sort ordering that equates all sorts. We start by computing the following initial DP problem: P1. (1) f91#(n) => cond#(n <= 100, n) (2) cond#(true, n) => f91#(n + 11) (3) cond#(true, n) => f91#(f91(n + 11)) ***** We apply the Theory Arguments Processor on P1. We use the following theory arguments function: cond# : [1, 2] f91# : [] This yields the following new DP problems: P2. (1) f91#(n) => cond#(n <= 100, n) (2) cond#(true, n) => f91#(n + 11) { n } (3) cond#(true, n) => f91#(f91(n + 11)) { n } P3. (1) cond#(true, n) => f91#(n + 11) (2) cond#(true, n) => f91#(f91(n + 11)) ***** No progress could be made on DP problem P2.
