我们给出了一个简单的证明,证明了具有多个顶点的凸多面体的归一化体积与多个简单集的混合体积相等,从而说明了计算简单集的混合体积这一看似具有限制性的问题至少仍然和一般的凸多面体的计算体积一样难。
qaaa We provide a simple proof for the equality between the normalized volume of a convex polytope withmvertices and the mixed volume ofmsimplices and thus show the seemingly restrictive problem of computing the mixed volume of simplices is still at least as hard as computing volumes of convex polytopes in general.
