The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(1, n^2).


The TRS R consists of the following rules:

if(true, t, e) → t
if(false, t, e) → e
member(x, nil) → false
member(x, cons(y, ys)) → if(eq(x, y), true, member(x, ys))
eq(nil, nil) → true
eq(O(x), 0(y)) → eq(x, y)
eq(0(x), 1(y)) → false
eq(1(x), 0(y)) → false
eq(1(x), 1(y)) → eq(x, y)
negate(0(x)) → 1(x)
negate(1(x)) → 0(x)
choice(cons(x, xs)) → x
choice(cons(x, xs)) → choice(xs)
guess(nil) → nil
guess(cons(clause, cnf)) → cons(choice(clause), guess(cnf))
verify(nil) → true
verify(cons(l, ls)) → if(member(negate(l), ls), false, verify(ls))
sat(cnf) → satck(cnf, guess(cnf))
satck(cnf, assign) → if(verify(assign), assign, unsat)
