Besides, we prove that SSLS has the superior performance both in the theoretical part and empirical part.\n  In this paper, we prove that the probability of adaptive elastic net selecting wrong variables can decays at an exponential rate with very few conditions. Irrepresentable Condition or similar constraint isn't necessary in our proof.
