How to prove that every polynomial in an infinite family is irreducible over Q?
In view of Noam Elkies' perfect answer, I removed my answer. Also, his construction of the auxiliary polynomial is similar, but more efficient than Runge's original argument. |

How to prove that every polynomial in an infinite family is irreducible over Q?
@Noam D. Elkies: I did not obtain the bound $10^{20000}$ from Runge, rather I doubted that carrying out Runge's algorithm would be that bad. Indeed, arxiv.org/abs/math/0512418 might be interesting in this regard. |

Integer roots of a polynomial
It still looks like an odd question. For instance $p=j=1$ and $a_1=-1/2$ is a solution, and I doubt that something clever can be said about all the possible solutions. |

Determine if a graph has a large clique
The little known program MaxCliqueDyn to be found at sicmm.org/~konc/maxclique often supersedes cliquer. Maybe it helps in your situation. |

Number of Permutation with at-most K cycles . (Elements Repeated)
This is the same question as the recently closed mathoverflow.net/questions/157516/…! It fails in many regards to be a reasonable MO question. |
