Viviane语言竞争模型的位串及其他改进
Bit-strings and other modifications of Viviane model for language competition
摘要：
Viviane de Oliveira等人的语言竞争模型通过将每种语言与32位的字符串相关联来修改。在Viviane模型中，每当语言发生变化时，也会翻转一个随机选择的位。如果只有具有不同位串的语言才被视为不同，那么由此产生的语言大小分布与经验观察到的略微不对称的对数正态分布一致。也尝试了其他几种修改，但要么有更多的自由参数，要么不太符合现实。
英文摘要：
The language competition model of Viviane de Oliveira et al is modified by associating with each language a string of 32 bits. Whenever a language changes in this Viviane model, also one randomly selected bit is flipped. If then only languages with different bit-strings are counted as different, the resulting size distribution of languages agrees with the empirically observed slightly asymmetric log-normal distribution. Several other modifications were also tried but either had more free parameters or agreed less well with reality.
