is an international journal on Combinatorics and Theory of Computing  published by János Bolyai Mathematical Society and Springer Verlag

  publishes research papers in English in a variety of areas of combinatorics and the theory of computing, with particular emphasis on general techniques and unifying principles. Typical but not exclusive topics covered by  are:

  • Combinatorial structures (graphs, hypergraphs, matroids, designs, permutation groups).
  • Combinatorial optimization.
  • Combinatorial aspects of geometry and number theory.
  • Algorithms in combinatorics and related fields.
  • Computational complexity theory.
  • Randomization and explicit construction in combinatorics and algorithms.
