Center node: "computing balanced islands in two colored point sets in the plane"
  Abstract: Abstract   Let S be a set of n points in general position in the plane, r of which are red and b of which are blue. In this paper we present algorithms to find convex sets containing a balanced number of red and blue points. We provide an    O  (    n    4    )    time algorithm that for a given    α  ∈   [  0  ,    1    2    ]     finds a convex set containing exactly    ⌈  α  r  ⌉    red points and exactly    ⌈  α  b  ⌉    blue points of S. If    ⌈  α  r  ⌉  +  ⌈  α  b  ⌉    is not much larger than      1    3    n   , we improve the running time to    O  (  n  log  ⁡  n  )   . We also provide an    O  (    n    2    log  ⁡  n  )    time algorithm to find a convex set containing exactly    ⌈    r  +  1    2    ⌉    red points and exactly    ⌈    b  +  1    2    ⌉    blue points of S, and show that balanced islands with more points do not always exist.
