量子電腦x量化交易!?
最近一個禮拜,我參加了台大 IBM-Q 舉辦的量子電腦黑客松,並列第一名,並且額外獲得鴻海特別獎。我們這組從零開始,只花了三天,也學到很多量子電腦的知識,還有認識新朋友,覺得非常的開心!
以前的黑客松,比較偏工程,想做什麼就做什麼,天馬行空,但是這次的黑客松,跟以往非常不一樣,有很多數理的成分,更重視理論,我們組的學歷陣容非常堅強,兩個博後,一個博士,兩個碩士,除了我以外,都是物理專長。討論的都是 Ising model、QAOA、quantum gate 等物理的概念。
我一開始真的是不懂,從 0 開始,好在 IBM 有出 Python 的 Package Qiskit,我看得懂程式和演算法,原來 Ising model 可用於解 maximum cut problem,原來 QAOA 可用於 Binary 的 quadratic optimizer,那我就把它們當成黑盒子,大概可以理解並應用了。
我很慶幸在博士班的時候,有把數學更徹底的學好一點,所以才能在這麼優秀的團隊中,貢獻所學的知識。在比賽中,我的專長,就是提供創意且實際的主題,跟寫浮誇程式介面XD,也是黑客松比賽非常重要的兩個要素。這次也很成功的繳出一張滿意的成績單!
經過這次的戰役,我人生中參加 4 次現場黑客松,4 次都有得獎,3 次是第一名,一大部分原因,是我歷史上參與比賽的伙伴,陣容都是非常堅強,有堅強的學術背景,工程技術,而且團隊向心力強,不會輕易放棄,肝也非常新鮮健康。我也有所貢獻,但是每一個人都缺一不可,都是比賽的致勝關鍵。讓我回想到那些一起熬夜寫程式的日子,真是太辛苦又太有成就感了!
雖然比賽很好玩,但我很少參加,因為平常已經夠忙了,做交易就已經很像是黑客松了!但是這次是我老婆邀請我去,剛開始勉為其難的答應,因為我真的不懂量子電腦,怕現醜。我老婆常會逼我做一些不想做的事情,但最後往往會有正向的回報,所以我常常會聽從老婆的決定,尤其是比較重大的決定XD,有她的主意,我的人生更精彩!所以既然要做,就要全力以赴,PyCon演講完回到台北,就馬上出發參加比賽。
不過這大概是我參加過,最不像黑客松的比賽了,早上七點起床,搭遊覽車到「台大溪頭自然教育園區」,都已經中午了!三天的比賽,其中半天搭車去,半天搭車回台北,都在搭車就好啦!不過搭車是活動的一部分,總比自行前往好很多吧!
於是我們就在山明水秀中討論數學、寫程式,也別有一番風味,但是物理界的黑客松風格,真的是跟一般的黑客松有很大的差異!一般黑客松,吃的都是垃圾食物,像是PIZZA,漢堡之類的,但在物理黑客松,竟然是吃合菜,很好吃!以前的黑客松,只有一間教室跟一堆二手睡袋,看你要不要睡,不睡拉倒。而這次竟然睡飯店!每個人竟然有一張雙人床可以睡,被單還可以控制溫度!
而且這個活動是免費的!!你或許會覺得,政府和學校又再浪費國家公帑了,讓學生們吃喝玩樂,花納稅人的錢,但其實,這是很聰明且省力的作法,就像是投資股票,要把錢砸在好的公司身上,讓這些頂尖的腦袋在舒服的環境下,請他們做一些科學上的突破,成效真的非常好,有鑑於這次的成果,IBM 決定在台灣2021年再辦一場,更大且國際級的量子電腦黑客松,各國頂尖學者聚集於台灣,產生的週邊效益,對於台灣科技的進步,絕對是一筆超級划算的投資!
我已經很久沒有接觸交易以外的程式了,這個禮拜出來玩三天,又可以得獎,算是一個另類的抒壓!平常都在製作交易程式,琢磨賺錢的程式很辛苦,本身的程式實力當然很重要,但有時候找到對的交易策略,就是需要長時間的琢磨,運氣成分也非常高,而最後如何判斷程式運行的是正確的?就是有沒有賺到錢囉!XD,但價格通常是隨機漫步,所以你真的很難確定,新程式能幫你賺錢,除非運行了一陣子,就算能賺錢,你還是會擔心它可以幫你賺多久,日子就在「擔心」的循環中度過。
寫一般的程式,就沒有這麼辛苦了,你得到的 feedback 是非常迅速且即時的,可以用就是可以用,不能就是不能,可以根據這個 feedback 快速優化程式,這就其實是寫程式最開心的地方,藉由不斷修正,程式變得越來越多功能,越來越好!
然而這次的比賽如何獲勝呢?量子電腦,目前真的還在傳統電腦真空管的時代,我覺得這次要得獎有兩種不同的方法,第一種,對於量子電腦的電路製作有真正的貢獻,第二種,將量子電腦做跨領域的結合。第一種對我來說比較困難,要在短時間瞭解各種不同的量子閘,並且做出量子電腦的具體貢獻,短時間不太可能,第二種,是我比較擅長的,就是做跨領域結合,將量子電腦的演算法用在不同的地方。
我們將資工系常見的感測器網路當作命題,做出車聯網的應用,利用量子力學的演算法,來做都市規劃建構感測器網路,為車聯網做提前的佈局,和計算感測器資料同步協定。另外也做了其他的應用,利用量子電腦做車輛定位(我承認這部分用量子電腦做沒有必要XD(沒有quantum advantage),但最後demo很炫就是了)。
在三天的時間裡,應用量子電腦的演算法,構建三種車聯網應用,相信是個很完整的結果!我們將競賽成果開源到github上,供大家下載下來玩,不過程式碼還有很多優化空間,請大家小力鞭策XD!

之後會介紹跟量子電腦和這次黑客松有關的系列文章,也會講一些量子電腦用於程式交易的演算法,不過假如你期望量子電腦可以幫你拿來賺錢,看到這裡就好了,因為不太可能,量子電腦還在很早期的階段,就像是電腦在真空管的時代。但你假如你對數學不排斥,想要瞭解一些量子演算法,這個系列應該會很有趣!

เกมเมอร์พบบั๊กโมเดลตัวละครเพี้ยนใน Death Stranding หากไม่อัปเดตไดรเวอร์การ์ดจอ
.
Chris Person นักข่าวใน Kotaku ได้ค้นพบบั๊กสุดขำขันในเกม Death Stranding เวอร์ชัน PC ที่โมเดลร่างกายตัวละครในเกมมีลักษณะยืด หรือโพลิกอนแตกทั้งในฉากคัตซีนและเกมเพลย์
.
หลังจาก Person ประสบเจอปัญหาดังกล่าว เขาได้ลองสอบถามหลายคนเกี่ยวกับปัญหาด้าน Performance จากเกมดังกล่าว ซึ่งทุกคนก็ตอบกลับว่าไม่พบปัญหาบั๊กระหว่างการเล่นแต่อย่างใด เขาจึงค้นพบทีหลังว่าบั๊กนี้เกิดขึ้น เป็นเพราะ PC ของเขาลืมทำการอัปเดตไดร์เวอร์การ์ดจอเป็นเวอร์ชันล่าสุดนั่นเอง

Death Stranding เวอร์ชัน PC เพิ่งออกวางจำหน่ายเมื่อช่วงคืนวันที่ 14 กรกฎาคม โดยเกมดังกล่าวมีกระแสรีวิวชื่นชมทั้งฝั่งผู้เล่นกับนักวิจารณ์ในด้าน Optimization และภาพกราฟิกที่ยกระดับความลื่นไหล และสวยงามไปอีกขั้นหนึ่ง เพราะฉะนั้นใครที่กังวลว่าเกมเวอร์ชัน PC จะพอร์ตแย่ก็หายห่วงกันได้เลย
.
ถือว่าเป็นบั๊กประหลาดที่สร้างเสียงหัวเราะให้ผู้เล่นไม่มากก็น้อย ถ้าหากเกมเมอร์เจอปัญหาดังกล่าว ก็ลองอัปเดตไดร์เวอร์การ์ดจอเป็นเวอร์ชันล่าสุด ซึ่งอาจทำให้บั๊กดังกล่าวหายไป

Gamer meets cuddle model. Crazy character in Death Stranding. If it doesn't update, screen card drivers.
.
Chris Person, a journalist in Kotaku, found a funny cuddle th in Death Stranding game. PC version that modeled the characters in the game, stretched or polygon, both in the cuddle th scene and gameplay.
.
After Person suffered such a problem, he asked many people about Performance issues from the game. Everyone replied that there was no cuddle kg problem during playing. So he found out later that this cuddle th is because of PC. He forgot to update the cuddle screen card driver to the latest version.

Death Stranding PC version just released on the night of July 14 This game is trendy. Player s' reviews with Optimization critics and graphics that raise fluidity and beauty to another level of beauty. Anyone who is concerned that the PC version of the game will be bad, don't worry about it.
.
It's considered a freaky cuddle that creates laughter for players. Otherwise, if gamers encounter such problems, try cuddle update screen card drivers to the latest version which may make cuddle press cuddle so far. Let's go.

Kawasaki 750RS (..floatage.. Arles) and Kawasaki and Z750FOUR (Zet ..floatage.. Fo) are motorcycles of total displacement 746cc that were manufactured and sold from 1973 Kawasaki to 1978.
Outline
The alias is "Z2 Zetts. " ..("Zettots" or "It is often called Arles (From 750RS of the car name)) in Kansai it... Because Z1 of displacement 903cc was put on the market in 1972, and the gain sales results were also good, and the motorcycle of 750cc or more was not able to sell high popularity by the self-imposed restraint of the industry (large-scale automatic operation two wheel reference) in Japan in Europe and America, the domestic version model of 750cc class was necessary for Kawasaki. Both the boa and the stroke were changed after all and it optimized it as 750cc model though it was scheduled to down the engine of Z1 in the boa at first and to put it on the market. Marvelous sales were achieved at first of the Japan sale, and it became a great car that invented a lot of legends.
Optimization of engine boa/stroke
The reduction to 750cc by the down of the boa was not in view though a Square engine of 66×66mm boa/stroke of Z1(903cc) of the base model, and expected by the expansion to about 1000cc by the boa improvement in the future. The change in the stroke cannot help doing the crank shaft as a complete new design, and it is very disadvantageous in the point of time and cost. However, when it is adjusted to about 750cc only the boa down, it becomes about 60mm, and, with this, the boa diameter :.
* The new design of the cylinder head is needed so that exhaust valve may
interfere as it is.
* It becomes a long stroke, and it is unsuitable for the image of "High power
car".
Therefore, the reduction of the boa selected the method of stopping within the range where the cylinder head was able to be used as it is, changing the crank instead, and reducing the stroke.
The displacement was improved to Z1000, and two Z900 for export was made a muffler at the same time in 1976(model in 1977). However, even four Z750FX sales in 1979 kept defending the style of the muffler as for Z750FOUR (The model name changes in 1976) for Japan.
The model cycle is exceptional ..continuing for eight years like the same basic the engine and the frame until the model disappears as Z750FX(Z750 D3) in 1980.. as the motor cycle of comparatively short Japan.
Moreover, after the production of main bodies of the vehicle ends, it is familiar with the rearview mirror designed for Z1 and Z2 long by the name of "Z2 mirror" (Zettsumirar) in the articles market.
It can be difficult to take the large-sized car the production discontinuance this time about the problem of the license system and it be hardly reflected by the secondhand market because it was at the time of the new model rush such as HONDA and CB750Four. However, the one that was 200,000 yen or less till then came for the sudden rise in the influence of the cartoon or the secondhand car market to start in around 1987, and to reach as much as 800,000 yen by this level, too. Still, two wheels magazine at that time is fueled what , saying that "In addition, rise if it doesn't buy it now". Moreover, Z1 was assumed beginning at this time, and a lot of phenomena motorcycles' produced at the motorcycle and the local factory that had been exported to foreign countries visiting Japan came to be seen. It has dealings over the vehicle where the level is good at a high price by an initial type more than the new car of a present this class as of now. Moreover, it is big existence as it becomes the motif of the styling of Zefarshirez as one of the models in which the motorcycle of Kawasaki is symbolized now.
It is still said that it often appears in the drama and the cartoon, and it is set as past image or hot-rodder's own car.
It is additionally equipped from the anxiety of the battery and the charge system to reliability with the kick-starter though the self starter by the starter motor was widespread at the Z2 sale this time.
