Theme Algorithmics, Graphs, Complexity


The AGC team focuses on algorithmic in graphs, lattices and geometry. It involves studying structural  properties  in order to design efficient algorithms. The main orientations are:
  1. Enumeration of combinatorial objects in graphs and efficient algorithms for optimization or counting problems.
  2. Representations of lattices and efficient algorithms for lattices.
  3. Structures and decompositions of graphs.
  4. Algorithmic of objects from geometry.
The team is also interested in applications in data mining and data quality.
