Writing Update

I spent a lot of time jumping around and filling things in for the eventual beta, plus working on Chapter 12's first draft. I shooould technically be prepping Chapter 11 for its alpha but I've got time for that later. Inspiration was striking me now and I gotta follow the muse ^_^

Incidentally, I've never fully understood the concept of a muse, so if anyone has any thoughts on what mine should be feel free to assign me one 😂

Here's this week's preview :)

S_R Bookshelf by Konstantin Slawinski

This is the most minimalistic bookshelf possible. The GermanDesigner Konstantin Slawinski created the S_R bookshelf in three sizes and three colors, white, grey and black. All shelves are a simple steel wire, bend in a smart way. Minimalism in it’s most purest form.

(via https://www.youtube.com/watch?v=s_R-SEjhIRo) I have always loved Alec and his character developement to the moon and back, but this amazing video by Martinca really made me realize how much shit and accusations he had to deal with…and the most of it he did silently. I am so happy that he found Magnus and eventually got some appreciation from the people close to him.

Mackup for ever

#Mackup for ever skin#

Her lazy day makeup consists of the coveted concealer and their Cloud Setting Powder, which gives the illusion that you have no pores or dark circles. And yes, I’m blaming HB for all of Kosas’ Revealer Concealer being sold out in Sephoras everywhere. Kosas - have gained traction over time as she highlights her daily routines in which Kosas is typically front-and-center. She’s literally perfect and if a model puts it on, I’ll probably trust it. The public devours anything and everything Hailey Bieber puts on her flawless face at any given moment. Hot girl celebrities like HB, Olivia Wilde, and Gwyneth Paltrow all wear it, so I feel fairly confident in claiming that we should too. Excuse me while I breathe a sigh of relief.Ī brand that's passionate about the environment, your skin, and the way you feel when you wear their makeup doesn’t come easily. Kosas is made by people with sensitive skin, so their makeup won’t clog pores or cause a massive breakouts the next day. What’s even better about the brand is that they boast clean ingredients. With or without the endorsements, Kosas products are cutting-edge and high quality without breaking the bank into a million pieces.

A member of the niche, yet elusive group of those who find brands before celebs. I could’ve been one of those “I-knew-Kosas-before-Hailey Bieber” people. I didn’t think there was anything that needed to be fixed.īecause Tiktok, much to my chagrin, wasn’t the end of While I was okay being comfortable with familiarity from brands like Benefit, Makeup Forever, and Tarte, I didn’t know I could - and should - elevate my routine. Take this as my public apology to the brand. I’m ashamed to admit I knocked Kosas before I tried it. If I didn’t know you, you weren’t worth my time. I used to write off any new makeup brand that didn’t have reputations or stamps of approval. I didn’t care that this revolutionary product would make me look beautiful. I didn’t care about up-and-coming brands that could change the way I view makeup. They made your skin glow, but didn’t give off an oily sheen that most do. A few months back, I remember a Tiktok of someone plugging these new skin tint drops that would change the game.

S_R is vegetarian (possibly vegan). Not out of morals, but out of ick. Also after a lifetime of State rations and a general view of food as inconvenient method of refueling, he’s also got a palette that it’d be generous to describe as ‘bland’.

He likes salt. He’d like cheese, as long as no one told him how it was made.

Honestly his ideal food would be crisp sandwiches.

Writing Update

This was a very eclectic round of writing. I hopped to the epilogue chapter and coded out a few possible endings and wrote some of the RO-based conversations, including fleshing out one I'd already begun. Then it was time to spend some more energy on chapter 9, which I've come to accept as "this is my life now." 😂

Here's this week's preview :)

ABC107D - Median of Medians

ABC107D - Median of Medians

自分の考えつく領域を超えていたので頭の中の整理として。

問題リンク

https://atcoder.jp/contests/abc107/tasks/arc101_b

考え方

与えられた数列aから切り出せる連続部分列の中央値を全通り集めた数列mについて、 mの中央値は何？という問題。 切り出せる連続部分列全通りを試していては間に合わないので工夫が必要。

考え方を変えてみて、 「数列mの中央値をある値Xにすることはできるか？」という判定問題を考える。 「数列mの中央値がXである」を言い換えると、「数列mにはX以上の要素が半分以上ある」となる。

数列mは数列aから切り出せる連続部分列の中央値を集めたものであり、 数列aからの切り出し方は ${}_{N+1}C_2$ 通りあることを考えると、 「数列aから切り出した数列について、X以上の要素が半分以上となるような切り出し方が $\frac{{}_{N+1}C_2}{2}$ 通り以上あるか？」と言い換えられる。

数列aの各要素について、X以上の要素は1に、X未満の要素を-1に置き換える。 このとき、「X以上の要素が半分以上となるような切り出し方」は 「総和が0以上となるような切り出し方」に言い換えられる。

累積和 $S_i=A_0+A_1+\cdots+A_i$ を考えると、 「総和が0以上となるような切り出し方」は「 $S_r-S_l \geq 0$ を満たす(l,r)の組」と言い換えられる。 $S_r-S_l\geq0$ は式変形して $S_l \leq S_r$なので、 「累積和の各要素について、自分より後ろかつ自分以上の値である要素の数」を求めることになる。

ここで転倒数を考えてみる。 転倒数は「自分より後ろかつ自分未満の要素の数」のことであり、今求めたいものの余事象にあたる。 そのため、求めたい値は「 ${}_{N+1}C_2$ -転倒数」になる。

「 ${}_{N+1}C_2$ -転倒数」=「数列mのX以上の要素数」なので、 「 ${}_{N+1}C_2$ -転倒数 $\geq \frac{{}_{N+1}C_2}{2}$ 」を満たすXの最大値が答えになる。 これはにぶたんで求められる。

実装では転倒数を求める際にBITを用いており累積和が負になると都合が悪いため、 累積和の各要素にNを加えて0以上となるよう下駄を履かせている。

提出コード https://atcoder.jp/contests/abc107/submissions/9331987

おまけ

「自分より後ろかつ自分以上の値である要素の数」を転倒数で求める代わりに ウェーブレット行列で殴ることもできる。 計算量は悪化するが、求めたい値を言い換えなしに直接計算できる。

提出コード https://atcoder.jp/contests/abc107/submissions/9332056

自分は「数列aの各要素について中央値に何回選ばれるか」を考えていたが計算量が落とせず失敗。 解きやすい形に言い換えを重ねていく点が自分では思いつけなかったところだった。 「中央値��X＝X以上の要素が半分以上」の言い換えも別の問題でも使えそう。

Is $S_R$ finitely generated? https://ift.tt/eA8V8J

Suppose $S_R$ - is the set of all total recursive bijections on $\mathbb{N}$. It is not hard to see that this set forms a group with respect to composition, and that $|S_R| = \aleph_0$. Is $S_R$ finitely generated?

The group $S_R$ contains the group $S_\infty$ (the group of finitely based bijections) as its subgroup, which is infinitely generated. However, there exists $S_\infty < H \leq S_R$, such that $H$ is finitely generated. The $H$ can be described as $\langle (01), f \rangle$, where $f$ is defined by formula:

$$f(x) = \begin{cases} 0 & \quad x = 0 \\ 2 & \quad x = 1 \\ x + 2 & \quad x \geq 2 \text{ and is even} \\ x - 2 & \quad x \geq 2 \text{ and is odd} \end{cases}$$

Indeed, $\forall x = 2n+1$ $(0x)=(01)f^{n}$ and $\forall x = 2n$ $(0x)=(01)f^{-n}$. Hovever, this does not give us the answer to the question as $H$ is most likely a proper subgroup of $S_R$ (though, i do not know for sure).
