'''Simplexity''' is a [[neologism]] which proposes a possible complementary relationship between [[complexity]] and [[simplicity]].

One of the first formally published instances of the word was in the journal 'Childhood Education' (1924), in the article it appears to be used to discuss education and psychology related issues.<ref name="unknown">(Unknown). [https://books.google.com/books?id=d5vHZ2xXBa0C&q=simplexity Childhood Education] Published 1924. Association for Childhood Education International.</ref>

Simplexity was defined by computer scientists [[Andrei Broder|Broder]] and [[Jorge Stolfi|Stolfi]] as: "The simplexity of a problem is the maximum inefficiency among the [[wikt:reluctant|reluctant]] algorithms that solve P. An algorithm is said to be [[wikt:pessimal|pessimal]] for a problem P if the best-case inefficiency of A is asymptotically equal to the simplexity of P."<ref name="Broder">Broder, Andrei and Jorge Stolfi. [http://portal.acm.org/citation.cfm?coll=GUIDE&dl=GUIDE&id=990536 "Pessimal Algorithms and Simplexity Analysis."]</ref>

In 1974 [[Rustum Roy]] and Olaf Müller noted simplexity in the structure of [[ternary compound]]s: "By dealing with approximately ten ternary structural groupings we can cover the most important structures of science and technology specific to the non-metallics world. It is a remarkable instance of nature's 'simplexity'".<ref>[[Rustum Roy]] & Olaf Müller (1974) ''The Major Ternary Structural Families'', pages 3 & 4, Springer-Verlag {{ISBN|9780387064307}}</ref>

In 2003 Philippe Compain in an article on the future of synthetic chemistry stated: "Simplexity may be defined as the combination of simplicity and complexity within the context of a dynamic relationship between means and ends.";<ref name="Compain">[http://www.lactualitechimique.org/spip.php?numero_article437 Philippe Compain "The challenge of simplexity. The simple and the complex in organic synthesis" Act. Chim., 2003, 263-264, pages 129-134.]</ref><ref name="pCompain">[http://pubs.rsc.org/en/content/articlelanding/2006/nj/b601837h#!divAbstract Philippe Compain et al.

''Simplexity: Why Simple Things Become Complex (and How Complex Things Can Be Made Simple)'' by [[Jeffrey Kluger]] details ways in which simplexity theory can be applied to multiple disciplines. Kluger offers a look at simplexity at work in economics, sports, linguistics, technology, medicine and human behavior.

Simplexity has been used by [[Jens Nordvig]] to describe the particular aim of his analytics firm Exante Data."A research product that draws on a very complex analytical foundation, but is presented in a very simple and easy to digest manner"<ref>{{Cite news|url=https://exantedata.com/news/letter-simplexity-in-research|title=Letter: Simplexity in Research|work=exante data|access-date=2018-05-03|publisher=Exante Data|language=en-US}}</ref>

Dan Geesin first used the term 'Simplexity' in his essay 'The melancholy of the set square', 2002, when describing how technology creates more distance through complex interfaces whilst performing a simple task. For example, getting money from a bank machine. He describes how in between the chain of interfaces there is more room for error. More interfaces, more potential problems.
