随机2CSP的SDP值

The SDP value of random 2CSPs

Amulya Musipatla, Ryan O'Donnell, Tselil Schramm, Xinyu Wu

摘要:

我们考虑了一类非常广泛的模型稀疏随机布尔2CSP,相当于,度2优化问题的~ $\{\pm 1\}^n$。对于每个模型$\mathcal{M}$,我们确定自然SDP弛豫的“高概率值”~ $s^*_{\mathcal{M}}$(相当于量子值)。也就是说,对于所有的$\varepsilon > 0$,我们证明了随机$n$变量实例的SDP最优值(当通过~ $n$归一化时)在$(s^*_{\mathcal{M}}-\varepsilon, s^*_{\mathcal{M}}+\varepsilon)$范围内具有高概率。我们的一类模型包括非规则CSP,和SDP松弛值严格小于谱松弛值的模型。

英文摘要:

We consider a very wide class of models for sparse random Boolean 2CSPs; equivalently, degree-2 optimization problems over~$\{\pm 1\}^n$. For each model $\mathcal{M}$, we identify the "high-probability value"~$s^*_{\mathcal{M}}$ of the natural SDP relaxation (equivalently, the quantum value). That is, for all $\varepsilon > 0$ we show that the SDP optimum of a random $n$-variable instance is (when normalized by~$n$) in the range $(s^*_{\mathcal{M}}-\varepsilon, s^*_{\mathcal{M}}+\varepsilon)$ with high probability. Our class of models includes non-regular CSPs, and ones where the SDP relaxation value is strictly smaller than the spectral relaxation value.
