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.
