  Abstract: Abstract   Let  S  be a planar  n -point set. A  triangulation  for  S  is a maximal plane straight-line graph with vertex set  S . The  Voronoi diagram  for  S  is the subdivision of the plane into cells such that all points in a cell have the same nearest neighbor in  S . Classically, both structures can be computed in    O  (  n  log  ⁡  n  )    time and    O  (  n  )    space. We study the situation when the available workspace is limited: given a parameter    s  ∈  {  1  ,  …  ,  n  }   , an  s -workspace algorithm has read-only access to an input array with the points from  S  in arbitrary order, and it may use only    O  (  s  )    additional words of    Θ  (  log  ⁡  n  )    bits for reading and writing intermediate data. The output should then be written to a write-only structure. We describe a deterministic  s -workspace algorithm for computing an arbitrary triangulation of  S  in time    O  (    n    2    /  s  +  n  log  ⁡  n  log  ⁡  s  )    and a randomized  s -workspace algorithm for finding the Voronoi diagram of  S  in expected time    O  (  (    n    2    /  s  )  log  ⁡  s  +  n  log  ⁡  s    log    ⁎    ⁡  s  )   .
