    • An effective model to decompose linear programs for parallel solution 

      Pınar, Ali; Aykanat, Cevdet (Springer, 1996-08)
      Although inherent parallelism in the solution of block angulax Linear Programming (LP) problems has been exploited in many research works, the literature that addresses decomposing constraint matrices into block angular ...
    • Fast shared-memory streaming multilevel graph partitioning 

      Jafari, N.; Selvitopi, O.; Aykanat, Cevdet (Elsevier, 2020-09-12)
      A fast parallel graph partitioner can benefit many applications by reducing data transfers. The online methods for partitioning graphs have to be fast and they often rely on simple one-pass streaming algorithms, while the ...
    • Multilevel cluster ensembling for histopathological image segmentation 

      Şimşek, Ahmet Çağrı (Bilkent University, 2011)
      In cancer diagnosis and grading, histopathological examination of tissues by pathologists is accepted as the gold standard. However, this procedure has observer variability and leads to subjectivity in diagnosis. In order ...
