Description
The longest path problem is the problem of finding a path of maximum length in a graph.
A graph $G$ is called interval graph if its vertices can be put in a one-to-one correspondence with a family $F$ of intervals on the real line such that two vertices are adjacent in $G$ if and only if the corresponding intervals intersect; $F$ is called an intersection model for $G$.
Parameters
$n$: number of vertices
$m$: number of edges
