Let $ABCDE$ be a convex pentagon with $AB=14,$ $BC=7,$ $CD=24,$ $DE=13,$ $EA=26,$ and $\angle B=\angle E=60^{\circ}.$ For each point $X$ in the plane, define $f(X)=AX+BX+CX+DX+EX.$ The least possible value of $f(X)$ can be expressed as $m+n\sqrt{p},$ where $m$ and $n$ are positive integers and $p$ is not divisible by the square of any prime. Find $m+n+p.$

Let $\mathbb{N}$ be the set of positive integers. A function $f:\mathbb{N}\to\mathbb{N}$ satisfies the equation \[\underbrace{f(f(\ldots f}_{f(n)\text{ times}}(n)\ldots))=\frac{n^2}{f(f(n))}\]for all positive integers $n$. Given this information, determine all possible values of $f(1000)$.

Oliforum contest - 5th edition (31 January 2017)
bboypa   2
N Feb 6, 2017 by bboypa
Hello guys,

I am back with, I hope, a good new. There will be in nearly one month the 5th edition of the "Oliforum contest". It is an individual and telematic contest, with some training problems at national/imo level. Maybe it can be useful to some forumers around here. :)

Some details below:

1- The contest is made by a unique round, starting in the early afternoon of Tuesday 31 January and ending at 23:59 of Sunday 05 February (Rome meridian +1GTM) (in practice, 5.5 days).

2- Every problem will have some points, from 0 to 7. One additional point could be given for each clear, correct, and original solution.

3- There are no age contraints.

4- Non-olympic arguments could be used, even if it is preferred to not do it.

5- It is enough to send the solutions by mail, at the address that you can find below. Enrollment is not necessary.

6- Time of incoming solutions will be considered only for ex-aequo positions.


7- How to send solutions.
- You need to send solutions to the following mail: $\text{ leonetti.paolo (AT) gmail.com }$.
- Solutions need to be attached in a unique attached .pdf file with a reasonable size.
- The .pdf file must be written with $\LaTeX$ or in a way that can be easily understood.
- You have to rename the .pdf file with the nickname that you have here on MathLinks.
- Try to be clear everytime.

Previous editions: { Ed. 2008, round 1, round 2, round 3 } , { Ed. 2009, round 1, round 2 }, { Ed. 2012 round 1 }, { Ed. 2013 round 1 }.

I will add below the list of problems on the 7th February, together with the list with people who sent correctly their solutions. Comments and suggestions are welcome.

Cheers,
Paolo Leonetti
