This is not the same as Create a Simon Clone! because this is a simplified text version of Simon. Your goal is to make a simple stdin/stdout (or equivalent input/output) Simon clone. The buttons are represented by 0,1,2,3. The program works like this: main: start lives at 3 start number array ...

@Lembik Hi?

Bas

@CᴏɴᴏʀO'Bʀɪᴇɴ hi, you're hard to ping. Everything after C breaks

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Bas Indeed. Just do @C + tab

Bas

@CᴏɴᴏʀO'Bʀɪᴇɴ I wanted to change my name to C to prevent people from pinging you but then I remembered the 1 month namechange rule

Cᴏɴᴏʀ O'Bʀɪᴇɴ

XD. then it's just @C + tab * n

Q: Calculate the Kronecker Product

Related, but very different. In the examples below, A and B will be 2-by-2 matrices, and the matrices are one-indexed. A Kronecker product has the following properties: A⊗B = A(1,1)*B A(1,2)*B A(2,1)*B A(2,2)*B = A(1,1)*B(1,1) A(1,1)*B(1,2) A(1,2)*B(1,1) A(1,2)*B(...

@Sp3000 Hello!

zyabin101

@Bas The <center> cannot hold it is too late.

Damn very slow 'net connection!

Lembik

@Sp3000 I haven't managed to write the matrix mult challenge

one question is should it be multiplication over the integers or something simpler?

TimmyD

@Bas Reminds me of House of Leaves

zyabin101

I tried to install Anaconda (actually its small no-package niece Miniconda) and all I got was megabytes of disk space wasted. I am never able to use conda.

Now I have to reinstall Python FROM THE VERY BEGINNING (as I uninstalled the CPython distro for conda to be available from the system PATH, as a second variation) ;;;_;;;

Sp3000

13:06

@Lembik Does it matter? Or is the answer somehow different if you work in, say, integers mod 2 or something?

Nathan Merrill

13:30

is there a good reason python uses __magic__ for their magic methods as opposed to just magic

a.add(b) is much more readable than a.__add__(b)

Kenny Lau

Since when did answers in Jelly become unpopular?

Lembik

13:48

@Sp3000 I think the answer might be the same but the code could be a lot faster. How are you going to search for solutions if you use integers?

Sp3000

Well the answer you get shouldn't really depend on the contents of the matrix, right? As in it should just give a list of intermediate steps and how to obtain each entry in the resulting matrix

Lembik

@Sp3000 right but I am trying to imagine how you are going to solve the problem of finding the minimum number of multiplications

@Sp3000 do you have any ideas?

Sp3000

Not any good ones, no, but I was assuming that was part of the challenge :P

Lembik

it is :)

Sp3000

I mean, in the worst case you could just brute force all possibilities for a solution

Obviously not the best way

Lembik

13:52

so one idea I have works mod 2 but not with integers

@Sp3000 how will you check a given solution is correct even if you use brute force?

Sp3000

As in that it's optimal or that it's a valid solution?

Lembik

brute force is OK for small n :)

@Sp3000 that it's valid

basically.. what is a brute force solution?

Agawa001

i object

Lembik

@Agawa001 ?

Sp3000

Check that it indeed outputs C_{1,1} = A_{1,1} B_{1,1} + A_{1,2} B_{2,1} etc

Agawa001

13:54

bruteforce isnt ok unless for np hard problems

Lembik

@Sp3000 but you can't check all A_{i,j} if it's allowed integer entries

that's the problem

you can if it's only allowed zeros and ones

Sp3000

Well you don't care about the actual values right? As in you don't sub A_{1,1} for a number, just treat it as A_{1,1}

Lembik

@Sp3000 that sounds hard :)

zyabin101

I'm interested - if a Python install for Windows is repaired, will any packages installed before the repair remain?

Sp3000

Well you wanted a possible approach, and that's the only one I have in mind atm :P

zyabin101

13:56

(Repairing an install is the Windows Installer's way of saying "to re-install".)

Sp3000

@Agawa001 It's good for checking your better approach is correct for at least small values though

Lembik

@Sp3000 I like the idea but I am not sure how easy it would be to prove your solution is equivalent to A_{1,1} B_{1,1} + A_{1,2} B_{2,1} in code

zyabin101

\o/ @RenderSettings you're back!

Lembik

without enumerating alll possible entries

Agawa001

@Sp3000 how ?

zyabin101

13:57

Apparently not. Dam.

Agawa001

ah, make a comparative with the outlets of two approaches

Sp3000

@Lembik Er... maybe I'm not saying this clear enough. Imagine starting with 8 variables a,b,c,d,e,f,g,h and I define x = a(f-h), y = (a+b)h. Then it's pretty easy to check that x+y = af - ah + ah + bh = af + bh

RenderSettings

@zyabin101 im always already back

Cᴏɴᴏʀ O'Bʀɪᴇɴ

zyabin101

@CᴏɴᴏʀO'Bʀɪᴇɴ Ah, you are back. Did you see the countdown I announced for Nested Programs?

Sp3000

14:05

@Lembik Hmm maybe "8 symbols" is a bit clearer than "8 variables". But anyway for that example a is A_{1,1}, b is A_{1,2}, ... , e is B_{1,1}, ... , h is B_{2,2}

@Sp3000 gregorybard.com/papers/early_release.pdf

@Sp3000 I think there must be something wrong with what you said but I am not sure what yet :)

@Sp3000 and eprints.aston.ac.uk/19428/1/letter-18-04.pdf

it's that sort of thing I am talking about

Sp3000

Probably just some miscommunication going on here

Lembik

14:13

Most likely I am being dim

in any case.. I think it would make a nice challenge :)

if somewhat challenging challenge

Nathan Merrill

ok, there are 6 equality operators, ==, !=, <, <=, >, >=

Sp3000

Would be an interesting challenge, yeah

Nathan Merrill

however, they all have opposites

Sp3000

btw what I said was just saying it'd be easy to verify that a solution is correct, not that it helps at all in actually finding a solution (if that makes things any clearer)

Nathan Merrill

so, == is the opposite of !=, and < is the opposite of >=

would it make sense to only have magic methods for ==, <, > and simply not the result?

Sp3000

14:17

You could, which is why a lot of golfing langs only have < and >. But what's this for?

Lembik

@Sp3000 thanks.. things are a little clearer

I still think mod 2 is easier :)

Sp3000

I'm not sure how it'd be any different, but okay...

Lembik

so.. the question is do I have the time/energy to write the challenge! :)

Sp3000

:P if you do - and I don't usually say this - please do sandbox this one, since it's a bit too nice of a challenge to ruin

Cᴏɴᴏʀ O'Bʀɪᴇɴ

it's expiring soon

zyabin101

@CᴏɴᴏʀO'Bʀɪᴇɴ Apparently you own two blogs.

Agawa001

one is a website

zyabin101

@Agawa001 One is a blog.

It's easy to find out that codingspecialty.cf embeds in itself a Blogger blog, codingspecialty.blogspot.<your national TLD>.

That's a... nice strategy.

So @CᴏɴᴏʀO'Bʀɪᴇɴ, when the .cf domain expires, you should redirect users to the site codingspecialty.blogspot.<user's national TLD>.

Agawa001

@zyabin101 blogs are of the fom www.blog.com/myblog, whereas hosted blogs as myblog.blog.com (attached websites) are quasi independant because they are located in different server of the site
