Informed Search

Informed search is often referred toHeuristic Search. This algorithm searching use specific knowledge to the problems, this method able to find solutions more efficient than Uninformed strategy

Question and Assignment

The Flashlight Puzzle

Four people are on one side of a bridge. They wish to cross to the other side, but the bridge can only take the weight of two people at a time. It is dark and they only have one flashlight, so they must share it in order to cross the bridge. Assuming each person moves at a different speed (able to cross in 1, 2, 5 and 10 minutes, respectively), find a series of crossings that gets all four across in the minimal amount of time.

Solution

the point of this question is to find the fastest way to take 4 people to the other side of bridge
A : 1 minute
B : 2 minutes
C : 5 minutes
D : 10 minutes

A and B across the bridge	2 minutes
B bring back the flashlight	2 minutes
C and D across the bridge	10 minutes
A bring back the flashlight	1 minutes
A and B travel over	2 minutes
total	17 minutes

Code implementation using DrSceme

State representation must identify the locations of each person and the flashlight
((1 2 5 10) left ())
note : must be careful of permutations/ pertukaran urutan
e.g., (1 2 5 10) = (1 5 2 10) so must make sure there only one representation per set
Solution : maintain the list in sorted order, so only one permutation is possible
only 3 possible moves:
1. if the flashlight is on left and only 1 person on left, then
move that person to the right (cost is time it takes for that person)
2. if flashlight is on left and at least 2 people on left, then
select 2 people from left and move them to right (cost is max time of the two)
3. if the flashlight is on right, then
select a person from right and move them to left (cost is time for that person)
Heuristic:
H: number of people in wrong place

Part 1

Note: below questions based on course for the subject "Web Design Technology"
Conduct at khon kaen university 2014

1. Whar is Html?
HTML stand for hypertext markup language, that lets you identify common sections of a Web page

2. Write structure of a basic web page?
answer

3. What is head section?
the container for all of the descriptive information about the document

4. How the way Browser display Html?

• The browser interprets the HTML markup elements and displays the results, hiding the actual markup from the user
• Each browser interprets HTML in its own way, based on its rendering enginebased on its rendering engine
• It is essential that you test your work in different Web browsers

4. Write sort story about the Past HTML?
Tim Berners-Lee first proposed HTML at the European Laboratory for Particle Physics (CERN) in 1989

5. What is organitation which sets standars for HTML and other markup languages
World Web Consortium (W3C)

6. What is XML
XML stand for Extensible Markup Languages, it's essentiail to creating applications for the Web

7. 6 XML syntax rules

• Documents must be well-formed
• All tags must net properly and not overlap
• Use all lowercase for element names
• Always use closing tags
• Empety elements are signified by a closing slash
• Attribute values must be continued in quotation marks

8. 3 problem of using XHTML?

1. Relaxed syntax rules still must be applied because of legacy code 2. Newer versions of XHTML moved too far away from existing Web development 3. XHTML was not well received by the development community

9. What is WHATWG?
Web Hypertext Application Technology Working goup the one that purpose HTML 5

10. 2 types of HTML 5 syntax?
An HTML compatible syntax > more relaxed syntax, Code shortcut allowed
An XML compatible syntax > Consistent with XHTML, Uses XML syntax rules
