a territorial isolation is a danger to the game population, causing deterioration called the inbreeding depression. the typical signs are anomalous body proportions, such as short lower jaw, shortened lifetime, weak physique and lower birth rate. this is caused by low number of game in the community. white colored deer is in the location of the czechrepublicbred in separation since 18th century...

We study the computational complexity of $c$-Colored $P_\ell$ Deletion and $C_\ell$ Deletion. In these problems, one is given a $c$-edge-colored graph wants to destroy all induced $c$-colored paths or cycles, respectively, on $\ell$ vertices by deleting at most $k$ edges. Herein, path cycle if it contains edges $c$ distinct colors. show that are NP-hard for each non-trivial combination $\ell$. ...
