The Sznajd model implements a phenomenon called social validation and thus extends the Ising spin model. In simple words, the model states: * Social validation: If two people share the same opinion, their neighbors will start to agree with them. * Discord destroys: If a block of adjacent persons disagree, their neighbors start to argue with them. == Mathematical formulation == For simplicity, one assumes that each individual $i$ has an opinion Si which might be Boolean ($S\_i=-1$ for ''no'', $S\_i=1$ for ''yes'') in its simplest formulation, which means that each individual either agrees or disagrees to a given question. In the original 1D-formulation, each individual has exactly two neighbors just like beads on a bracelet. At each time step a pair of individual $S\_i$ and $S\_$ is chosen at random to change their nearest neighbors' opinion (or: Ising spins) $S\_$ and $S\_$ according to two dynamical rules: # If $S\_i=S\_$ then $S\_=S\_i$ and $S\_=S\_i$. This models social validation, if two people share the same opinion, their neighbors will change their opinion. # If $S\_i=-S\_$ then $S\_=S\_$ and $S\_=S\_i$. Intuitively: If the given pair of people disagrees, both adopt the opinion of their other neighbor. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sznajd model」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
