The particular model studied, termed the \"bar-attendance\" model, offers a simple paradigm for such complex adaptive systems involving competitive agents. The model considers p adaptive agents, each possessing n predic tion rules chosen randomly from a pool of N , who attempt to attend a bar where the seating capacity is s. The global attendance time-series x(t) has a mean near, but not equal to, s . Surprisingly, the standard deviation or \"volatility\" of x(t) can show a minimum with increasing adaptability of the individual agents. Various arguments based on random walk models are dis cussed. It is shown that effects of crowding have to be included in order to understand the volatil ity in this system.<\/jats:p>","DOI":"10.1177\/105971239900700302","type":"journal-article","created":{"date-parts":[[2007,3,11]],"date-time":"2007-03-11T01:45:25Z","timestamp":1173577525000},"page":"243-253","source":"Crossref","is-referenced-by-count":2,"title":["Global Behavior in a Population of Adaptive Competitive Agents"],"prefix":"10.1177","volume":"7","author":[{"given":"P.M.","family":"Hui","sequence":"first","affiliation":[{"name":"The Chinese University of Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.R.","family":"Kwong","sequence":"additional","affiliation":[{"name":"The Chinese University of Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ping","family":"Cheung","sequence":"additional","affiliation":[{"name":"The Chinese University of Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.F.","family":"Johnson","sequence":"additional","affiliation":[{"name":"University of Oxford"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1999,1,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.80.1385"},{"key":"atypb2","first-page":"406","volume":"84","author":"Arthur, W.B.","year":"1994","journal-title":"American Economic Review"},{"key":"atypb3","volume-title":"How Nature Works","author":"Bak, P.","year":"1997"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-4371(97)00401-9"},{"key":"atypb5","volume-title":"Adaptive Individuals in Evolving Populations","author":"Belew, R.K.","year":"1996"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1209\/epl\/i1997-00491-5"},{"key":"atypb7","first-page":"36","author":"Casti, J.","year":"1996","journal-title":"New Scientist"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-4371(97)00419-6"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-4371(98)00260-X"},{"key":"atypb10","volume-title":"Herd behaviour and aggregate fluctuations in financial markets","author":"Cont, R.","year":"1997"},{"key":"atypb11","volume-title":"Nonlinear Dynamics","author":"Epstein, J.M.","year":"1997"},{"key":"atypb12","doi-asserted-by":"publisher","DOI":"10.1038\/scientificamerican0394-76"},{"key":"atypb13","doi-asserted-by":"publisher","DOI":"10.1126\/science.162.3859.1243"},{"key":"atypb14","volume-title":"Hidden Order: How Adaptation Builds Complexity","author":"Holland, J.H.","year":"1995"},{"key":"atypb15","doi-asserted-by":"publisher","DOI":"10.1126\/science.277.5325.535"},{"key":"atypb16","doi-asserted-by":"publisher","DOI":"10.1142\/S0219525998000107"},{"key":"atypb17","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-4371(99)00073-4"},{"key":"atypb18","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-4371(98)00227-1"},{"key":"atypb19","doi-asserted-by":"crossref","DOI":"10.1093\/oso\/9780195079517.001.0001","volume-title":"The origins of order: Self-organization and selection in evolution","author":"Kauffman, S.","year":"1993"},{"key":"atypb20","volume-title":"Proceedings of the International Workshop on Econophysics and Statistical Finance"},{"key":"atypb21","volume-title":"Fundamentals of Statistical and Thermal Physics","author":"Reif, F.","year":"1982"},{"key":"atypb22","volume-title":"Adaptive competition, market efficiency, phase transition and spin-glasses","author":"Savit, R.","year":"1997"},{"key":"atypb23","volume-title":"Micromotives and Macrobehavior","author":"Schelling, T.C.","year":"1978"},{"key":"atypb24","volume-title":"Life's Other Secret: The new mathematics of the living world","author":"Stewart, I.","year":"1998"},{"key":"atypb25","volume-title":"Rationalizable Boundedly Rational Behavior","author":"Zambrano, E."}],"container-title":["Adaptive Behavior"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/105971239900700302","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/105971239900700302","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T16:18:28Z","timestamp":1777393108000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/105971239900700302"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1999,1]]},"references-count":25,"journal-issue":{"issue":"3-4","published-print":{"date-parts":[[1999,1]]}},"alternative-id":["10.1177\/105971239900700302"],"URL":"https:\/\/doi.org\/10.1177\/105971239900700302","relation":{},"ISSN":["1059-7123","1741-2633"],"issn-type":[{"value":"1059-7123","type":"print"},{"value":"1741-2633","type":"electronic"}],"subject":[],"published":{"date-parts":[[1999,1]]}}}
