Editing Convex hull (section)

==History==
The lower convex hull of points in the plane appears, in the form of a Newton polygon, in a letter from [[Isaac Newton]] to [[Henry Oldenburg]] in 1676.<ref>{{harvtxt|Newton|1676}}; see {{harvtxt|Auel|2019}}, page 336, and {{harvtxt|Escobar|Kaveh|2020}}.</ref> The term "convex hull" itself appears as early as the work of {{harvs|first=Garrett|last=Birkhoff|authorlink=Garrett Birkhoff|year=1935|txt}}, and the corresponding term in [[German language|German]] appears earlier, for instance in [[Hans Rademacher]]'s review of {{harvs|last=Kőnig|authorlink=Dénes Kőnig|year=1922|txt}}. Other terms, such as "convex envelope", were also used in this time frame.<ref>See, e.g., {{harvtxt|White|1923}}, page 520.</ref> By 1938, according to [[Lloyd Dines]], the term "convex hull" had become standard; Dines adds that he finds the term unfortunate, because the colloquial meaning of the word "hull" would suggest that it refers to the surface of a shape, whereas the convex hull includes the interior and not just the surface.{{sfnp|Dines|1938}}
