This is a very simple type of brute force searching techniques. The search begins by expanding the initial node i.e. by using an operator generate all successors of the initial node and test them. This procedure finds whether the goal can be reached or not but the path it has to follow has not been mentioned. Diving downward into a tree as quickly as possible performs DFS searches. Algorithm:

This is also a brute force search procedure like DFS. We are searching progresses level by level. Unlike DFS which goes deep into the tree. An operator employed to generate all possible children of a node. BFS being a brute force search generates all the nodes for identifying the goal. ALGORITHM:

Best-first search, rather than plunging as deep as possible into the tree (as in   depth-first search ), or traversing each level of the tree in succession (as in   breadth-first search ), uses a heuristic to decide at each stage which is the best place to continue the search. Best-first search in its most basic form consists of the following algorithm (adapted from   Pearl, 1984): The first step is to define the OPEN list with a single node, the starting node. The second step is to check whether or not OPEN is empty. If it is empty, then the algorithm returns failure and exits. The third step is to remove the node with the best score, n, from OPEN and place it in CLOSED. The fourth step “expands” the node n, where expansion is the identification of successor nodes of n. The fifth step then checks each of the successor nodes to see whether of not one of them is the goal node. If any successor is the goal node, the algorithm returns success and the solution, which c...

TCP UDP Reliability : TCP is connection-oriented protocol. When a file or message send it will get delivered unless connections fails. If connection lost, the server will request the lost part. There is no corruption while transferring a message. Reliability : UDP is connectionless protocol. When you a send a data or message, you don't know if it'll get there, it could get lost on the way. There may be corruption while transferring a message. Ordered : If you send two messages along a connection, one after the other, you know the first message will get there first. You don't have to worry about data arriving in the wrong order. Ordered : If you send two messages out, you don't know what order they'll arrive in i.e. no ordered Heavyweight : - when the low level parts of the TCP "stream" arrive in the wrong order, resend requests have to be sent, and all the out of sequen...
