I really enjoyed this video, thanks for sharing your story. I'm sure you realize by now that the entire purpose of such competitions is for people like yourself to have experiences like the one you described here. It doesn't matter what mathematical modeling is (well, it's important that _some_ people care about it, but that doesn't have to be you), and the medals themselves are without a doubt the least important part of the whole thing. You're on the right track (or, at least, _a_ right track)--just keep going!
As a 16 year old this video inspired me to work on the same problem. And I actually managed to prove an upper bound of cuberoot(7)^{(n+1)^2} SAW's on an n by n grid!
I really liked this video, it reminded me of when I was 14 years old and I became obsessed with mathematics, I was discovering new properties for myself, such as the polar formula of complexes or the generalizations of Pascal's triangle to higher dimensions, then I realized that they had already been discovered, anyway it was very fun, now I am studying mathematics and I am in the best stage of my life... :D

the only useful thing I independently rediscovered was binomial distribution when I was 13. I was thinking about the probability of getting exactly n times the number 2 after m rolls. the argument I had and the result was pretty much the exact same as the one you would find in most textbooks(don't know how I hadn't known about such a famous part of probability). I guess I got lucky knowing about pascal's triangle and its connection with combinations because I had no idea how to turn arithmetic sequences into closed forms.
This is also something I had also done. I meant the original work but figured out it was pretty much not original. So, I know how you feel. Good video though
جميل جداً أن يكون للشخص طموح ورغبة فيما يفعله، نعم مشكلة أن تكتشف شيئا بمفردك ثم تعثر على وجوده مسبقاً قد تسبب الإحباط بعض الشيء وقد حدثت معي بالفعل في عدد كبير من الأشياء، لكنه أيضا امر جميل، مشكلتك مثيرة للاهتمام وقد عمل عليها العديد من علماء الرياضيات وقد توصلت اليه بمفردك، هذا يدعو للفخر، بالنسبة لعدد المتاهات الممكنة لم أدرس الامر بعد ولكن يمكنني ذكر حل بسيط للغاية وهو أن كل خط في الشبكة إما أن يكون موجودا او غير موجود لذا له احتمالان، وبذلك عدد المتاهات الممكنة يساوي 2 مرفوعة لقوة عدد الخطوط، ولكن طبعاً هذا يتضمن متاهات تحوي مسارات مغلقة لا يمكن السير فيها، لمعرفة العدد المضبوط بتجنب تلك المتاهات علينا ان نطرح من الناتج عدد الحالات التي يكون هناك مربع لا يمكن التجول فيه، وعدد الحالات التي يكون هناك مربعين لا يمكن التجول فيهما وعدد الحالات التي هناك ثلاثة مربعات لا يمكن التجول فيها وهكذا.... ولكن كان لدي سؤال فيما مضى بخصوص المتاهات ولا أعتقد أنه صعب لكني لم أدرسه، وهو أنه إذا كان لديك حل معين لمتاهة تم اعطاؤه لك جبريا فكيف يمكنك تخفيض هذا الحل إن أمكن ذلك دون اللجوء إلى الرسم، يعني اكتشاف امكانية التخفيض وإجراء عملية التخفيض يجب أن تجري بطريقة جبرية، التخفيض طبعاً يتم من أجل التخلص من الخطوات التي تمت زيارتها أكثر من مرة أو الطرق المتقاطعة ذاتياً، اتمنى من يستطيع اجابتي ان يتفضل مشكورا وأيضا انا معجب حقا بشخص قام بهذه الاشياء بعمر ١٤ سنة
It sounds like you were young, learning, etc., so I don't think you should be too hard on yourself; that's how you learn to do research as I understand it: by preparing. Remenber, NOONE was born with the answers; not your professors not people with the gold medals, not John Nash or Riemann or Russell or whoever your favorite "rock stars" of Math are. (Except for Ramanujan, lol, he may have been born with a direct line and an operator connecting him to every integer lol. (No, he worked hard.)) The best part is your enthusiasm and while you may have coveted the awards or recognition of "big time" Mathematicians, I would wager that there are far more of them who might covet and envy your enthusiasm!! I mean this sincerely. Never stop loving that which you are passionate about!!!! 😀😀😀
Thanks for the word of encouragement! I have definitely been too hard to myself back then, but when I looked back, it is quite an achievement! The reason I have to self-deprecate a bit is just to make the video more interesting, though.

then going indirect as possible could deliver the right path. it is the route with the longest travel duration but with the shortest distance (a) the correct distance, wich is also the longest distance (b). depending on your navigation skills and manouvreability. 1.do you know where you are at any given point ? 2.do you know where you came from ? 3.do you know where you need to be ? 4.do you know you start time ? 5.do you know total travel time upfront ? 6.do you got countless trials ? like in how many trials do you must be correct. given it unlimted time and vectors. you will reach there merely by chance. even skipping a few wrong ways. i thought. in points coordinates i am on point a i want to go to point b there is a chance to get obstacles then i draw a straight line from a to b. then put an imagination point c there. so the route forms a triangle. then i dont go to point b. i go to 45 degrees or 90 degrees. under point b and then straight from point c to point b if there are more routes. it works for scouting. in a maze it was. always take a left turn or so. but your solution is way cool.

That's what I said - I really stopped learning *new maths* as in that I pretty much don't read university level maths in high school, and actually I learnt quite a lot just from solving problems.

You will not get anywhere without it, so learn it now, and learn it well.

So you can start on that. If you want to check out my video series on group theory, you could, but there are also other good resources of group theory out there :)

i also want to know that how you got this for your research means how you first find your research topic ........ btw what your age now
i whish i had like our math teacher who suggest me like this
so the right path is the longest path ?
then going indirect as possible could deliver the right path. it is the route with the longest travel duration but with the shortest distance (a) the correct distance, wich is also the longest distance (b). depending on your navigation skills and manouvreability.
1.do you know where you are at any given point ?
2.do you know where you came from ?
3.do you know where you need to be ?
4.do you know you start time ?
5.do you know total travel time upfront ?
6.do you got countless trials ?
like in how many trials do you must be correct. given it unlimted time and vectors. you will reach there merely by chance. even skipping a few wrong ways.
i thought. in points coordinates
i am on point a
i want to go to point b
there is a chance to get obstacles
then i draw a straight line from a to b.
then put an imagination point c there. so the route forms a triangle.
then i dont go to point b.
i go to 45 degrees or 90 degrees.
under point b
and then straight from point c to point b
if there are more routes.
it works for scouting.
in a maze it was. always take a left turn or so.
