Cimmeria (continent) Cimmeria (continent) Cimmeria was an ancient continent, or, rather, a string of microcontinents or terranes, that rifted from Gondwana in the Southern Hemisphere and was accreted to Eurasia in the Northern Hemisphere. It consisted of parts of what is today Turkey, Iran, Afghanistan, Tibet, Shan–Thai, and Malay Peninsula. Cimmeria rifted from the Gondwanan shores of the Paleo-Tethys Ocean during the Carboniferous-earliest Permian and as the Neo-Tethys Ocean opened behind it, during the Permian, the Paleo-Tethys closed in front of it. Cimmeria rifted off Gondwana from east to west, from Australia to the eastern Mediterranean. It stretched across several latitudes and
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
