CET classifies as feasible those functions whose most efficient algorithms have time complexity \(c \cdot n^k\) for arbitrarily large scalar factors \(c\) and exponents \(k\). This means that if a function is only computable by an algorithm with time complexity \(2^{1000} \cdot n\) or \(n^{1000}\), it would still be classified as feasible. This is so despite the fact that we would be unable to compute its values in practice for most or all inputs.
