## Parameter Hierarchy

A graph parameter is a function assigning an integer to each graph. A
graph parameter *a* can for each graph be smaller than another graph
parameter *b*, it can be always larger or *a* and *b* can be
incomparable. The relationship between different graph parameters is
useful when designing parameterized algorithms. In the graph
parameter hierarchy we gather several parameters and their relationships.
