Finding $k$-paths in cycle-free graph

In this thesis, we present two sub-linear time algorithms for finding paths of length $k$ in bounded-degree cycle-free graphs. The complexity of our algorithms is polynomially related to $k$, the degree bound, and the distance of the graph from being $k$-path free (i.e. having no simple paths of length $k$), denoted $\epsilon$. This improves over the known upper bound of $O(\frac{k \cdot d^k}{\epsilon})$ for the cycle-free special case.
