Australia (continent) meanings: travel writer Paul Theroux included New Zealand in his definition and others have used it for Australia, New Zealand and Hawaii. Another biologist, Richard Dawkins, coined the name "Australinea" in 2004. "Australia-New Guinea" has also been used. With a total land area of , the Australian continent is the smallest, and second-lowest human inhabited (after Antarctica) continent on Earth. The continental shelf connecting the islands, half of which is less than deep, covers some , including the Sahul Shelf and Bass Strait. As the country of Australia is mostly on a single landmass, and comprises most of the continent,
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
