Some stochastic model of rumours asserts that even an advanced communication network does not guarantee every agent hears certain news because they predict that rumour spreaders convert to stifflers when contacted with an informed agent. In this study, we adapted two rumour spread models to interstellar communication by developing an agent-based model (ABM) for exploring the issue more rigorously. We enhanced the spread models by adding two additional parameters called conversion probability and stop-criterion, which represent the eagerness and persistency of civilizations to establish new contacts. Results of the ABM under several settings suggest that limited SETI searches lead to undiscovered civilizations. Earth may be one of these undiscovered civilizations although an advanced communication network might already be set up. Hence, we speculate that rumour spread models can propose another solution to Fermi's Paradox.

使用谣言传播模型的基于代理的星际接触建模

一些谣言的随机模型断言，即使是先进的通信网络也不能保证每个代理人都能听到某些消息，因为他们预测谣言传播者在与知情代理人接触时会转变为僵硬者。在这项研究中，我们通过开发基于代理的模型 (ABM) 将两种谣言传播模型应用于星际通信，以更严格地探索该问题。我们通过添加两个称为转换概率和停止标准的附加参数来增强传播模型，这些参数代表了文明建立新联系的渴望和持久性。ABM 在几种设置下的结果表明，有限的 SETI 搜索导致了未被发现的文明。尽管可能已经建立了先进的通信网络，但地球可能是这些未被发现的文明之一。因此，
