人口协议中稳定的领导者选举需要线性时间

Stable Leader Election in Population Protocols Requires Linear Time

David Doty, David Soloveichik

摘要:

如果对于所有$n$,从每个$n$代理都处于相同状态的初始配置开始,以概率1到达正确(正好有一个代理处于特殊领导状态$\ell$)和稳定(从$\mathbf{y}$可到达的每个配置也具有处于状态$\ell$的单个代理)的配置$\mathbf{y}$,则填充协议 * 稳定地选举领导者 *。我们表明,任何人口协议,稳定地选出一个领导者需要$Ω(n)$预期的“并行时间”- $Ω(n^2)$预期总成对相互作用-达到这样一个稳定的配置。我们的研究结果也通知的理解的时间复杂度的化学自组织显示一个基本的困难,快速产生精确的数量的分子物种。

英文摘要:

A population protocol *stably elects a leader* if, for all $n$, starting from an initial configuration with $n$ agents each in an identical state, with probability 1 it reaches a configuration $\mathbf{y}$ that is correct (exactly one agent is in a special leader state $\ell$) and stable (every configuration reachable from $\mathbf{y}$ also has a single agent in state $\ell$). We show that any population protocol that stably elects a leader requires $Ω(n)$ expected "parallel time" --- $Ω(n^2)$ expected total pairwise interactions --- to reach such a stable configuration. Our result also informs the understanding of the time complexity of chemical self-organization by showing an essential difficulty in generating exact quantities of molecular species quickly.
