The Research on Legal Regulation about the Risk of Electronic Contract Error

Recently, there are ongoing legal issues about the electronic contract mistake. Due to the lack of relative law, it is difficult for judges to make the decision. According to the current legal practice around the world, judges are prone to change the traditional way to make the decision. They require enterprises to take the responsibility caused by the electronic contract mistake. This paper will discuss how to manage the risk of electronic contract mistake under the theory of risk management. In the first part we will discuss why we should use the theory of risk management to discuss this problem. In the second part, we will discuss the loophole in the current management of electronic contract. In the third part, we will discuss how to use the theory of risk management to manage the risk of electronic contract mistake

Boolean function monotonicity testing requires (almost) n1/2n^{1/2} non-adaptive queries

We prove a lower bound of $\Omega(n^{1/2 - c})$, for all $c>0$, on the query complexity of (two-sided error) non-adaptive algorithms for testing whether an $n$-variable Boolean function is monotone versus constant-far from monotone. This improves a $\tilde{\Omega}(n^{1/5})$ lower bound for the same problem that was recently given in [CST14] and is very close to $\Omega(n^{1/2})$, which we conjecture is the optimal lower bound for this model
