This problem has an interesting property. It is that if we know the longest weight to a leaf node then we can easily calculate the mininum number of minutes to check all of the transformers.
The property comes from the fact that if the technician want to exit from the ducts then the minimum number of minutes to check all the transformer is twice of the sum of all duct length. So the condition that the techinician doesn`t come out from the last leaf node means that the longgest way to reach for a leaf node lastly is the minimum path to visit all ducts.
So we can get the solution by ”subtract the maximum length to a leaf from the twice of sum of all ducts“.
Differences between
String.split() vs StringTokenizer
String.split() produces results including null string.
StringTokenizer skips null string.

I searched some papers about blog classificaion.
And I found some of them.
Here are list of the papers.
- Finding patterns in blog shapes and blog evolution, ICWSM `07
- Semi-Supervised Learning for Blog Classificatioin, AAAI `08
- Experiments with Mood Classification in Blog Posts, Stylistic Analysis Of Text For Information Access, `05
- BlogHarvest: Blog Mining and Search Framework, COMAD `06
I`ll read them until friday.
I`m in a confused situation, but I can avoid it by preparing myself.
First, I have to change my habits.
There is no workinig overnight.
Second, I have to improvement myself.
What abilities I have to improve?
- Reading English stuff speedly.
- Have a strong body.
- Think, and think, and think for my brain.
The above things that I mentioned can be accomplished by some plans.
To get speedy in reading, I`ll choose some papers that I`d seen.
And read the papers carefully focused on the expressions.
After that carefully think the main idea and what is the author`s thought.
And to have a strong body, I have to lead my self a regular life with some exercises.
Finally, that is awful thing. Because I can`t find the way to be.
I want to wake up my brain. But there is one thing obvious to me for it.
I have to have a strong body.
So I`ll focus on my habits and reading !!!
After busy days, I`ll execute the plan ASAP.
I saw this video so many times before when I need to be motivated.
I want to be a person who effects the world like Steve Jobs.
It is my ultimate goal.
It`s been a long time from my last post.
In these days I experienced so many things.
And I felt I have to be another man.
In the concrete, like sleeping early and get up early, …
And I got a idea to manage my time efficiently.
The keyword is no duplication when I`m doing something.
I think it will give me a great effect.
However, my plan started in here.
Now I know what to do and what I need.
Just need is my action.
I thought “fikachu” and answered to questions.
After some steps, the result of the system evaluated was “fikachu” ㅡㅡ;;
How can they do this? Is it an AI? … like machine learning? or data mining? …
I want to know all about the system.
Process
1. Search related works from open source or research.
2. Listing all requirements.
3. Design Architecture.
4. Implement & Testing
- Test 1
- http://www.ehow.com/
- Get well formed How-to documents
5. Implement my own requirements.
6. Test over the web sites.
*. go to next project …
The following is a link to 3rd Int’l AAAI Conference on Weblogs and Social Media.
And they offer a special data named ICWSM 2009 Spinn3r Blog Dataset.
It is a set of 44 million blog posts made between August 1st and October 1st, 2008.
And it is formatted in XML.
My question is how they crawling the data from web.
I need a lot of sufficient data set!
