基于博弈模型的復雜系統(tǒng)動力學研究
發(fā)布時間:2021-10-29 19:41
在任何一個存在著大量相互作用組分的系統(tǒng)中都會出現(xiàn)復雜行為,如固體中的原子相互作用,生物體中的細胞相互作用和經(jīng)濟生活中的消費者行為等都具有復雜性。近年來,人們對復雜系統(tǒng)的研究興趣不斷高漲,新的模型層出不窮,其中最引人注目的是一些傳統(tǒng)模型的推廣應用,如物理學中的伊辛模型,經(jīng)濟學中的少數(shù)者博弈模型,經(jīng)濟、生物、生態(tài)、以及社會學中廣泛應用的囚徒困境模型等,都被應用來分析復雜現(xiàn)象。在分析現(xiàn)實世界的一些復雜系統(tǒng)的特點和復雜現(xiàn)象出現(xiàn)的原因時,人們發(fā)現(xiàn)系統(tǒng)復雜行為的出現(xiàn)與系統(tǒng)的結(jié)構(gòu)有密切關系,從而導致了對網(wǎng)絡模型研究的熱潮。對網(wǎng)絡特性研究的成果進一步促使人們從網(wǎng)絡結(jié)構(gòu)的角度重新探討以往的復雜系統(tǒng)模型,空間博弈模型就是其中最為熱門的模型之一,激發(fā)了各個領域眾多科學家們的研究興趣。比較統(tǒng)計物理中以往所做的一些工作,我們發(fā)現(xiàn)這些空間博弈模型中出現(xiàn)的復雜行為與物理學中經(jīng)常討論的自組織現(xiàn)象和臨界行為十分相似,我們可以借助物理學中的相關概念和知識來分析這些復雜現(xiàn)象。而對空間博弈模型的研究反過來也能促使我們更深入地理解復雜的物理現(xiàn)象,如自旋系統(tǒng)和軟凝聚態(tài)中的一些問題。通過對少數(shù)者博弈模型和雪堆模型的研究,我們探討了...
