论文摘要

假设完整图的边缘是随机分别分配的,我们要求最小的重量跨越树,或完美匹配或哈密顿循环的重量。对于这些和其他几个常见的优化问题,当重量是对称随机变量的独立副本时,我们建立渐近紧密的边界(满足尾巴概率的轻度条件),尤其是当权重是高斯时。

Suppose that the edges of a complete graph are assigned weights independently at random and we ask for the weight of the minimal-weight spanning tree, or perfect matching, or Hamiltonian cycle. For these and several other common optimisation problems, we establish asymptotically tight bounds when the weights are independent copies of a symmetric random variable (satisfying a mild condition on tail probabilities), in particular when the weights are Gaussian.
