Tuesday 7 June 2016: All 172 of California's delegates to the Republican
National Convention are pledged to presidential contenders in today's
California Presidential Primary.
159 district delegates are to be bound to presidential contenders based on
the primary results in each of the 53 congressional districts: each
congressional district is assigned 3 National Convention delegates and the
presidential contender receiving the greatest number of votes in that
district will receive all 3 of that ... 阅读全帖

我一直有这么一个疑惑,首先,这delegate不是一张张抽象的票,而是一个个具体的人
,每人在convention上可以投一票,但bound的delegate在bound的轮次里得按初选的结
果投,这个理解对吧。
如果对,那么问题来了,那些被赢者通吃的州和区里的delegate很清楚该投谁,但那些
被按比例分配的州和区怎么办?比如昨天纽约州的某个区的结果是Trump拿到两票,
Kasich拿到一票。那到了Convention上,这三个delegate谁投Trump,谁投Kasich? 是
Trump和Kasich事先指定好,还是说到时候把这三人抽象地打成“一包选票”,就说你
甭管我们具体谁选谁,反正我们仨这轮两票归Trump,一票归Kasich? 当然数字上看,
这和指定好是等价的,但看上去挺滑稽的。
谁能释疑解惑一下?谢了。

我给你研究了一下:
The delegates were chosen over the weekend at the state Republican
convention, but they won't know who they're representing until the primary
results. Of the 41 elected delegates, 40 were Cruz supporters. However,
under party rules, each delegate is bound to the primary results for the
first round of voting at the national convention.
41个delegates 中,40个事ted支持者。但是,他们支持谁是不算数的。要看今天vote

第一张图所示路线是所有GPS和绝大多数司机默认走的一条路线,这条走I-78 W的路线
不比下图快很多,但是却多$4的过路费
第二张图的路线是可以节省至少$4过路费的路线:
1) South Bound从Holland Tunnel出来,靠左行驶进入US 1-9 South,然后进入1-9
South Express,一般并不经常堵车,堵车的是1-9 South Local,然后过了ERW机场的
出口靠右上NJ-81/I-95 Turnpike的ramp,然后就到收费站入口了
2) North Bound从I-95 N往NYC走,在13A出口出来,往NJ-81/Newark Liberty Airport
方向走,然后顺到US 1-9 North Express,最后进入Holland Tunnel前这段比I-78要快
堵车几率小很多

Better to convert eps files to pdf files first using epstopdf.
Then you can use pdflatex.
There maybe some bounding box issues but you can always edit
the eps file manually. The unit is 72 points/inch, very easy
to measure if you use something like visio to draw the figure.
Also if you are generating eps files from ps files, gswin32
can automatically decide the correct bounding box since

同意,并没要求最短。例如:
string = hohowl
pattern = howl
如果只要求lz说的true or false,这个肯定是true,但是如果要求最短的话,state
machine就得加入针对pattern首字符的reset。时间上应该是O(len(string))就好了。
第一题给的arrays是sort好的吗?是的话是不是可以这么做:
造个数组ind[n],每个元素初始化为某word第一次出现的index。然后记录ind[n]中最大/最小元素之差为distance。把最小元素move到该单词下一次出现的index,再算ind[n]中最大/最小元素之差,如果比distance小就替换掉。如此反复直到某次移动导致out of bound。(这个bound不是整个text的长度,而应该是某单词出现的次数)。如果有错还请指出

I don't think this will need DP eventually, coz it's too slow. Given n,
you need O(n) to compute f(n).
We know the 6-pattern
4 * f(n-6)
is giving the highest exponential rate. As a result, if the input n is
big, in the beginning we will always apply this pattern, until some
certain
point n0. So the end of the day, the time would be O(log(n)).
The next question is to give an upper bound of n0. One naive upper

另外一点,关于复杂度的分析:
log N^(1/2) + log N^(1/3) + ... + log N^(1/log N)
= log N (1/2 + 1/3 + ... + 1/log N)
一个很明显的 upper bound 肯定是 O( (log N)^2 ).
1/2 + 1/3 + ... + 1/log N
这个其实跟著名的 harmonic series 很类似:
http://en.wikipedia.org/wiki/Harmonic_series_%28mathematics%29
根据以上的文章,
1/2 + 1/3 + ... + 1/log N
= ln( log N ) + γ - 1 ,当 N 很大的时候
那么,一个比较 tight 的 upper bound 应该是:
O( log N * ln(log N) )

It is easy to come up with an $O(SL)$ algorithm for this problem but what is
good about this problem is that it actually has a linear time solution:
Let’s first make some notations clear:
1) |S| -> The length of S.
2) |L| -> The number of words in the list $L$.
3) $len_L$ -> The length of each string in $L$.
First we use an Aho-Corasick automaton to find out the occurrences of all
patterns. The time complexity of this step is $O(|S| + |L| * len_L + z)$
where $z$ is the number of output matches. ... 阅读全帖

其实好像是基本的平面几何问题啦,谁知道答案?
There is a rectangle (rectangle A) on a 2D space, with known width and
height.
Let's assume its upper left corner is (0, 0).
There is a point (point P) inside this rectangle, at (x,y).
Now, let's rotate rectangle A by k degree (k between 0 and 360), using point
P as center for rotation. For the resulting rectangle, let's get its
bounding rectangle as C.
Assume the bounding rectangle C's upper left point is our new (0, 0), what
are the new location of point A?

say push file with size F to N nodes, each node has download speed and
upload speed di and si, the lower bound of completion time is max{F/u_s, F/
min{di}, NF/(u_s + sum{ui})} and I think this lower bound can be achieved
closely.
example, F=16G, N=16, divide the file into 16 pieces
after 1s: each node has one piece
after 1s: each node has two pieces by exchanging (0-1, 2-3, etc)
after 2s: each node has four ((01)-(23), etc)
after 4s: each node has eight
after 8s: each node has 16
total 16s

直接这样是不对的吧...
貌似应该是先二分找到lower bound;然后在lower bound到n的范围内,再二分找到最
大的以prefix为前缀的串...
