Wikipedia / List of combinatorial computational geometry topics
List of combinatorial computational geometry topics enumerates the topics of computational geometry that states problems in terms of geometric objects as discrete entities and hence the methods of their solution are mostly theories and algorithms of combinatorial character.
See List of numerical computational geometry topics for another flavor of computational geometry that deals with geometric objects as continuous entities and applies methods and algorithms of nature characteristic to numerical analysis.

Minimal convex cover problem (NP-hard)
Tessellation problems
Shape dissection problems
Extremal shapes
Minimum bounding box (Smallest enclosing box, Smallest bounding box)
There are two common variants of this problem.
In many areas of computer graphics, the bounding box (often abbreviated to bbox) is understood to be the smallest box delimited by sides parallel to coordinate axes which encloses the objects in question.
In other applications, such as packaging, the problem is to find the smallest box the object (or objects) may fit in ("packaged"). Here the box may assume an arbitrary orientation with respect to the "packaged" objects.

2-D case: Maximum empty circle (largest empty circle)

Robust geometric computation addresses two main issues: fixed-precision representation of real numbers in computers and possible geometrical degeneracy (mathematics) of input data
