Production Systems:<br />
Systems that generate (produce) rules (states)  to reach a solution<br />
<br />
A production system  commonly consists of  following four basic components:<br />
1.  A set of rules of the form  CiAiwhere Cirefers to starting state and Airepresents consequent state. Also Cithe condition part and Aiis the action part. <br />
2.  One or more knowledge databases that contain whatever information is relevant for the given problem.<br />
3.  A control strategy that ascertains the order in which the rules must be applied to the available database<br />
4.  A rule applier which is the computational system that implements the control strategy and applies the rules to reach to goal (if it is possible).<br />

<b>State Space </b> </div>
<div>
</div>
<div>
State space search is a process used in which successive or statesof an instance are </div>
<div>
considered, with the goal of finding a goal statewith a desired property.</div>
<div>
</div>
<div>
State space search often differs from traditional  search (sequential, indexed sequential, </div>
<div>
binary search etc) methods because the state space is implicit: the typical state space </div>
<div>
graph is much too large to generate and store in memory. Instead, nodes are generated </div>
<div>
as they are explored, and typically discarded thereafter. </div>
<div>
</div>
<div>
E.g. in a tic tack toe game,  every move by a player forms a state space and the three  </div>
<div>
similar (O or X) consecutive  (row, column or diagonal)  symbolsforms goal state. </div>
<div>
</div>
<div>
In a chess game also state space forms a set of moves by players. </div>
<div>
</div>
<div>
We discuss water jug problem in the next section. </div>
</div>
<div>
<div>
State Space Search  </div>
<div>
The water jug problem:</div>
<div>
You are given two jugs, a 4-litre one and a 3-litre one. Neither has any measuring markers on it. There is a pump that can be used to fill the jugs with water. How can you get exactly2 litres of water into 4-litre jug. Let x and y be the amounts of water in 4-Lt and 3-Lt Jugs respectively Then (x,y) refers to water available at any time in 4-Lt and 3-Lt jugs. Also (x,y)       (x-d,y+dd) means drop some unknown amount d of water from 4-Lt jug and add dd onto 3-Lt jug. All possible production rules can be written as follows </div>
<div>
1.(x, y)→(4, y)       if x<4 4="" div="" fill="" ifx="" it="" nbsp="" remains="" to="" unchanged="" y=""></4><br />
<div>
2.(x, y)→(x, 3)if y<3 3="" div="" fill="" ify="" it="" nbsp="" remains="" to="" unchanged="" x=""></3><br />
<div>
3.(x, y)→(x −d, y)  if there is some water in 4 Lt jug, drop   </div>
<div>
if x >0some more water from it </div>
<div>
4.(x, y)→(x, y −d) if there is some water in 3 Lt jug, drop ify >0some more water from it </div>
<div>
5.        (x, y)→(0, y)  if there is some water in 4-Lt, empty it, y remains unchanged ifx >0 </div>
<div>
6.(x, y)→(x, 0)  if there is some water in 3-Lt, empty it, x remains unchanged ify >0 </div>
<div>
7.(x, y)→(4, y −(4 −x)) if there is some water in 3-Lt, the sum of ifx +y ≥4,y >0                                        water of 4-Lt and 3-Lt jug is >=4, then fill          water in 4-Lt jug to  its  capacity from 3-Lt jug </div>
<div>
8.(x, y)→(x −(3 −y), 3)  same as 7 with suitable change in x,y ifx +y ≥3,x >0</div>
<div>
9. (x, y)→(x +y, 0) if sum of water in both jugs <=4, then drop ifx +y ≤4,y >0 whole water from 3-Lt into 4-Lt </div>
<div>
10.(x, y)→(0, x +y) if sum of water in both jugs <=3, then drop ifx +y ≤3,x >0whole water from 4-Lt into 3-Lt </div>
<div>
11.(0, 2)→(2, 0) Transfer 2-Lt from 3-Lt jug into empty 4-Lt jug </div>
<div>
12.(2, y)→(0, y)  Empty 2 Lt water onto ground from 4-Lt jug without disturbing 3 Lt jug</div>
<div>
<br /></div>
<div>
Solution of Water Jug Problem Obviously to solve water jug problem, we can perform following sequence of actions, (0,0)      (0,3)      (3,0)      (3,3)      (4,2)      (0,2)    (2,0)  By applying rules 2,9,2,7,5 and 9 with initial empty jugs </div>
<div>
<br /></div>
<div>
<span style="color: #3d85c6;">Remember: There is NO hard and fast rules to follow this sequence. In any state space search problem, there can be numerous ways to solve, your approach can be different to solve a problem and sequence of actions too.  </span></div>
<div>
<br /></div>
<div>
State Space Search  Other problems </div>
<div>
<br /></div>
<div>
1. Cannibals and missionaries problems: In the missionaries (humans)and cannibals (human eaters) problem, three missionaries and three cannibals must cross a river using a boat which can carry at most two people. At any time number of cannibals on either side should not be greater than number of missionaries otherwise former will eat latter. Also The boat cannot cross the river by itself with no people on board.</div>
<div>
<br /></div>
<div>
2.    Tower of Hanoi Problem: It consists of three pegs, and a number of disks ( usually 60) of different sizes which can slide onto any peg. The puzzle starts with the disks in a neat stack in ascending order of size on one rod, the smallestat the top, thus making a conical shape. The objective of the puzzle is to move the entire stack to another rod, obeying the following rules:</div>
<div>
</div>
<div>
Only one disk must be moved at a time.</div>
<div>
</div>
<div>
Each move consists of taking the upper disk from one of the rodsand sliding it onto another rod, on top of the other disks that may already be present on that rod.</div>
<div>
</div>
<div>
No disk may be placed on top of a smaller disk.</div>
<div>
<br /></div>
<div>
3.  Monkey Banana Problem: A monkey is in a room. A bunch of bananas is hanging from the ceiling and is beyond the monkey's reach. However, in the room there are also a chair and a stick. The ceiling is just the right height so that a monkey standing on a chair could knock the bananas down with the stick. The monkey knows how to move around, carry other things around, reach for the bananas, and wave a stick in the air. What is the best sequence of actions for the monkey?</div>

The term <i style="box-sizing: border-box;">network programming</i> refers to writing programs that execute across multiple devices (computers), in which the devices are all connected to each other using a network.</div>
<div style="box-sizing: border-box; font-family: Verdana, Geneva, Tahoma, Arial, Helvetica, sans-serif; font-size: 15px !important; line-height: 24px; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
The java.net package of the J2SE APIs contains a collection of classes and interfaces that provide the low-level communication details, allowing you to write programs that focus on solving the problem at hand.</div>
<div style="box-sizing: border-box; font-family: Verdana, Geneva, Tahoma, Arial, Helvetica, sans-serif; font-size: 15px !important; line-height: 24px; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
The java.net package provides support for the two common network protocols:</div>

Socket Programming:</h2>
<div style="box-sizing: border-box; font-family: Verdana, Geneva, Tahoma, Arial, Helvetica, sans-serif; font-size: 15px !important; line-height: 24px; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
Sockets provide the communication mechanism between two computers using TCP. A client program creates a socket on its end of the communication and attempts to connect that socket to a server.</div>
<div style="box-sizing: border-box; font-family: Verdana, Geneva, Tahoma, Arial, Helvetica, sans-serif; font-size: 15px !important; line-height: 24px; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
When the connection is made, the server creates a socket object on its end of the communication. The client and server can now communicate by writing to and reading from the socket.</div>
<div style="box-sizing: border-box; font-family: Verdana, Geneva, Tahoma, Arial, Helvetica, sans-serif; font-size: 15px !important; line-height: 24px; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
The java.net.Socket class represents a socket, and the java.net.ServerSocket class provides a mechanism for the server program to listen for clients and establish connections with them.</div>
<div style="box-sizing: border-box; font-family: Verdana, Geneva, Tahoma, Arial, Helvetica, sans-serif; font-size: 15px !important; line-height: 24px; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
The following steps occur when establishing a TCP connection between two computers using sockets:</div>
<ul class="list" style="box-sizing: border-box; color: #313131; font-family: Verdana, Geneva, Tahoma, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 22px;">
<li style="background-attachment: initial; background-clip: initial; background-image: url("/images/icon-bullet.png"); background-origin: initial; background-position: 0px 4px; background-repeat: no-repeat; background-size: initial; box-sizing: border-box; color: black; line-height: 24px; list-style: none; margin-bottom: 5px; padding: 0px 0px 0px 19px;"><div style="box-sizing: border-box; font-size: 15px !important; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
The server instantiates a ServerSocket object, denoting which port number communication is to occur on.</div>
</li>
<li style="background-attachment: initial; background-clip: initial; background-image: url("/images/icon-bullet.png"); background-origin: initial; background-position: 0px 4px; background-repeat: no-repeat; background-size: initial; box-sizing: border-box; color: black; line-height: 24px; list-style: none; margin-bottom: 5px; padding: 0px 0px 0px 19px;"><div style="box-sizing: border-box; font-size: 15px !important; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
The server invokes the accept() method of the ServerSocket class. This method waits until a client connects to the server on the given port.</div>
</li>
<li style="background-attachment: initial; background-clip: initial; background-image: url("/images/icon-bullet.png"); background-origin: initial; background-position: 0px 4px; background-repeat: no-repeat; background-size: initial; box-sizing: border-box; color: black; line-height: 24px; list-style: none; margin-bottom: 5px; padding: 0px 0px 0px 19px;"><div style="box-sizing: border-box; font-size: 15px !important; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
After the server is waiting, a client instantiates a Socket object, specifying the server name and port number to connect to.</div>
</li>
<li style="background-attachment: initial; background-clip: initial; background-image: url("/images/icon-bullet.png"); background-origin: initial; background-position: 0px 4px; background-repeat: no-repeat; background-size: initial; box-sizing: border-box; color: black; line-height: 24px; list-style: none; margin-bottom: 5px; padding: 0px 0px 0px 19px;"><div style="box-sizing: border-box; font-size: 15px !important; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
The constructor of the Socket class attempts to connect the client to the specified server and port number. If communication is established, the client now has a Socket object capable of communicating with the server.</div>
</li>
<li style="background-attachment: initial; background-clip: initial; background-image: url("/images/icon-bullet.png"); background-origin: initial; background-position: 0px 4px; background-repeat: no-repeat; background-size: initial; box-sizing: border-box; color: black; line-height: 24px; list-style: none; margin-bottom: 5px; padding: 0px 0px 0px 19px;"><div style="box-sizing: border-box; font-size: 15px !important; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
On the server side, the accept() method returns a reference to a new socket on the server that is connected to the client's socket.</div>
</li>
</ul>
<div style="box-sizing: border-box; font-family: Verdana, Geneva, Tahoma, Arial, Helvetica, sans-serif; font-size: 15px !important; line-height: 24px; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
After the connections are established, communication can occur using I/O streams. Each socket has both an OutputStream and an InputStream. The client's OutputStream is connected to the server's InputStream, and the client's InputStream is connected to the server's OutputStream.</div>
<div style="box-sizing: border-box; font-family: Verdana, Geneva, Tahoma, Arial, Helvetica, sans-serif; font-size: 15px !important; line-height: 24px; margin: 0em 0.2em 1em; padding: 0px; text-align: justify; word-wrap: break-word;">
TCP is a twoway communication protocol, so data can be sent across both streams at the same time. There are following usefull classes providing complete set of methods to implement sockets.</div>
<h2 style="box-sizing: border-box; color: #121214; font-family: Verdana, Geneva, Tahoma, Arial, Helvetica, sans-serif; font-size: 1.7em; font-weight: normal; left: 0px; letter-spacing: -1px; line-height: 1.5em; margin: 0.2em 0.2em 0.2em 0px; padding: 0px; position: relative; text-shadow: rgb(204, 204, 204) 1px 1px 2px;">
