Australia (continent) Australia (continent) The continent of Australia, sometimes known in technical contexts by the names Sahul, Australinea or Meganesia to distinguish it from the country of Australia, consists of the land masses which sit on Australia's continental shelf. This includes mainland Australia, Tasmania, and the island of New Guinea (comprising Papua New Guinea and two Indonesian provinces). Situated in the geographical region of Oceania, it is the smallest of the seven traditional continents in the English conception. The continent lies on a continental shelf overlain by shallow seas which divide it into several landmasses—the Arafura Sea and Torres Strait between mainland
Smallest-circle problem on "N". The algorithm is recursive, and takes as arguments two (finite) sets of points and ; it computes the smallest enclosing circle of the union of and , as long as every point of is one of the boundary points of the eventual smallest enclosing circle. Thus, the original smallest enclosing circle problem can be solved by calling the algorithm with equal to the set of points to be enclosed and equal to the empty set; as the algorithm calls itself recursively, it will enlarge the set passed into the recursive calls until it includes all the boundary points
