On the Hegselmann-Krause conjecture in opinion dynamics 摘要 我们给出了Hegselmann和Krause在观点动力学中关于对称有界置信区间模型的一个猜想的一个初步证明：如果存在一个真理，并且所有个体都以远离零的正数量认真对待对方，那么所有真理寻求者都将收敛到真理。在这里，真理寻HDU3792 Twin Prime Conjecture【筛选法+前缀和】

Goldbach's conjecture is one of the oldest unsolved problems in number theory and in all of mathematics. It states: Every even integer, greater than 2, can be expressed as the sum of two primes [1]. Now your task is to check whether this conjecture h九度OJ题目1440-Goldbach's Conjecture
