Sándor Kisfaludi‑Bak

Among other things, my research is focused on the following topics:

• Structure and algorithmic properties of geometric intersection graphs
• Problems on point sets and objects in Euclidean and non-Euclidean spaces, such as the traveling salesman and Steiner tree
• Parameterized, exact and approximation algorithms on planar graphs and their generalizations
• Non-Euclidean (especially hyperbolic) computational geometry
