no wonder. none of this names sounds remotely chinese

You're a smelly, dumb undergrad scum who only has a superficial familiarity with big names from popsci sources.

Are you lonely?

>>8597041
no

I am playing vanilla WoW (blizzlike) on a private server called Elysium PvP, though. It just came out Saturday and nobody is level 60 yet

Have fun.

Thank you

Sorry, I was making a joke. Those algorithms are currently famous for kicking a bunch of asses at Go, they're not at all ideal for this. I'm not nearly knowledgeable to actually make any actually good suggestions.

Although, I guess it'd be interesting to see how well MCTS actually does at box packing. I can't see any reason it wouldn't work.

Make AIs do stuff, you can easily make something that seems complicated as fuck

before?
shit. you are an undergrad and you are nothing. then you get accepted and you instantly become important. you are wined and dined at school visits and its awesome. so fucking cool. its like being flown around the countries for parties in your celebration for being accepted

>during
you are paid to do research in a field I hope you enjoy. thats not a bad deal in itself. but you made it with the devil. you are required to work. hard. everyday. 10 - 12 hour days on average + classes and TAing. it can be crushing at times how stressed you feel. but there are many positives and it is an adventure.

>after
hopefully you chose an area in applied research so your degree isnt fucking useless. if you did, then money will come. if you didnt then you fall into the PhD glut along with the organic PhDs and theoretical people.

I want to get a PhD but I can't get my shit together. I'm still undergrad though, I think I have time.

It helps that it is only book.

Yes.
Yes.
But the latter is promising to be a HUGE cash drain with no benefit to it

Elon is a smart man. He likes to gamble. He likes to gamble with your money.
Thing is if he wins, don't expect him to write you a cheque. If he loses, did he really?
Like I said, smart man.
P.S. you're already nearly 5 billion in the hole with him. That would equal a lot of infrastructure projects.

Play some calm music and study. Studying is really relaxing for me if I'm not cramming for a test.

>>8591156
But it's really intensive when studying technical stuff, how is it relaxing?

Pop 30mg of Ritalin, crack open a fresh pack of cigs, toss on some upbeat rock music (think Andrew W.K.)

Computer Engineering/Math double major here, 4.0 GPA (so far)

I think I have seen this crap on some of the new children's math homework.


Won't they need to switch back to a normal system after learning this?


I don't know, but it seems kind of dumb honestly...

>>8600678
Isn't this system used in digit remembering contests(memory contests in general)?

I don't know where else it can be useful

>>8600681
Yes I think so, but is it useful to teach children?

If you guys don't know Irodov, which I'm gonna assume is true for most people, tell me a good problem solving book in Physics and books that should be able to help you solve it.

>>8600606

Being a super genius?
I mean, most people take years to achieve what you just wrote.

Stop shitposting on /sci/, not good for your soul.

>>8600618

Are you bragging for knowing Irodov? Hilarious.

>>8600559
Okay let me try again. It now looks like my only problems are due to my sloppiness, which is only half of the story.

There is also an aspect of me having just a hard time solving stuff I know in theory. I'm sure some of my fellow brainlets understand.

I know the simple answer to my problems is: "practice, practice, practice", but there must be more to it than that. What mindset do you guys try to get in when solving a problem?

>>8600559
Oh, hello. I wasn't aware there was another around here, or did I make you? Oh well.

Hello. My name is Simon. Would you like me to help you?

There are rules to help write readable math and to help reduce error.

You are hired!

Alright, first line of business. I just need you to bend over as you prepare yourself to be "mentored" by our highly paid baby boomer. Uh, no, no, you do not need pants for this.

>>8600451

What kind of background do you have? I always heard you need both mathematical and algorithmic tricks to solve the later problems.

>>8600465
Currently doing Masters in CS in a top 10 CS university. During my undergraduate degree I was a major in CS with a minor in mathematics @ 3.8 GPA but a good amount of extra-curricular experience. Just wondering how seriously do people take Project Euler in the real world. Maybe I'd have spent my time better reading Knuth? Who knows. But now I want to know what it was worth.

>>8600401

kek, not very different. The knowledge you have is mostly stored in the properties of the membranes of your neurons. So the membranes probably look different, but you wouldn't really see any difference in terms of the anatomy.


Kudos though.

>>8600412
I didn't mean a change in anatomy, but I was wondering whether there would be more visible activation in the parts of the brain associated with maths.

>>8600430


Hmm... likely... Higher level activity is a little harder to observe with current technologies though.


Observations are usually seen through these sequence of events:

1. If you use areas of your brain often, then those areas become more easily activated.
2. With more activity more blood is, on average, required to deliver nutrients to those regions (e.g. oxygen).
3. With more blood being sent to those regions, the changes can be tracked over time using magnetic resonance of the hemoglobin in the blood (using brain scanning tech).


I don't know which regions are associated with mathematical reasoning, but these researchers from Stanford apparently have a "hunch":

https://www.bostonglobe.com/ideas/2015/09/17/this-your-brain-math/WMrjRMIyyBmtJCLhb5m2FM/story.html


They list:

- the posterior parietal cortex
- the ventrotemporal occipital cortex
- the prefrontal cortex


Those areas of the brain are associated with higher level reasoning and high level mental visualization abilities.

>>8600372

Just sign in and see. I don't think you need that much at first.

If you are don't like math, that might be a good way to prepare for your future classes...

I think Project Euler looks fun, but does it really help with interviews? I have never heard of anything like that. It probably doesn't.

>>8600372
you can just wikipedia most of everything

first problem:
is (number) modulus 3 OR 5 == 1?
then add it to sum

loop that 1000 times
