Let $p(x)$ be an integer polynomial with $m\ge 2$ distinct roots $\alpha_1,\ldots,\alpha_m$ whose multiplicities are $\boldsymbol{\mu}=(\mu_1,\ldots,\mu_m)$. We define the D-plus discriminant of $p(x)$ to be $D^+(p):= \prod_{1\le i

根聚类的D加判别和复杂性

假设$ p(x)$是一个整数多项式,具有$ m \ ge 2 $个不同的根$ \ alpha_1,\ ldots,\ alpha_m $,其多重性为$ \ boldsymbol {\ mu} =(\ mu_1,\ ldots,\ mu_m )$。我们将$ p(x)$的D加判别式定义为$ D ^ +(p):= \ prod_ {1 \ le i
