Control strategies help determine which rules to apply next in problem solving. They are classified as uninformed/blind search strategies, which do not use additional information to guide the search, or informed/directed search strategies, which use heuristics to prefer certain nodes. Breadth-first search (BFS) and depth-first search (DFS) are examples of uninformed strategies, while best-first search and A* are informed strategies. BFS explores all nodes at the current depth before moving to the next depth, guaranteeing to find the shortest path if a solution exists. DFS explores nodes as deeply as possible before backtracking, using less memory but risking getting stuck in blind alleys.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Andreas Schleicher presents at the OECD webinar ‘Digital devices in schools: detrimental distraction or secret to success?’ on 27 May 2024. The presentation was based on findings from PISA 2022 results and the webinar helped launch the PISA in Focus ‘Managing screen time: How to protect and equip students against distraction’ https://www.oecd-ilibrary.org/education/managing-screen-time_7c225af4-en and the OECD Education Policy Perspective ‘Students, digital devices and success’ can be found here - https://oe.cd/il/5yV
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.

Unit 8 - Information and Communication Technology (Paper I).pdfThiyagu K
This slides describes the basic concepts of ICT, basics of Email, Emerging Technology and Digital Initiatives in Education. This presentations aligns with the UGC Paper I syllabus.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
1. Control strategies
Helps usdecidewhich rule toapply next.
What todowhen there are more than 1 matching
rules?
Good control strategyshould:
1.cause motion
2.Systematic
2. Control strategies are classified as:
1. Uninformed/blind search controlstrategy
Do not haveadditional infoaboutstates beyond problem def.
Total search space is looked for solution
No info is used todetermine preference of onechild over
other.
Example: 1. Breadth First Search(BFS), Depth First
Search(DFS).
4. 2. Informed/Directed Search Control Strategy
Some info about problem space(heuristic) is used to
computepreference among thechildren forexploration
and expansion.
Examples: 1. Best First Search, 2. ProblemDecomposition,
A*, Mean end Analysis
Heuristic function:
It mapseach state toa numerical valuewhich depicts
goodness of anode.
H(n)=value
Where ,
H() is a heuristicfunctionand ‘n’ is the currentstate.
5. Ex: in travelling salesperson problem heuristic value
associated with each node(city) might reflect
estimated distanceof thecurrent node from thegoal
node.
The heuristic we use hereis called HSLD Straight line
Distance heuristic.
7. Breadth First Search (BFS)
Algorithm:
1. Createavariable NODE_LISTand set it to
initial state.
2.Until a Goal State is found or NODE_LIST is
empty:
A) Remove the first element from NODE_LIST
amd call itas ‘E’. If the node listwas empty then
Quit.
B) Foreach way thateach rulecan match thestate
described in ‘E’ do:
i) Apply the rule togenerate the new state
Ii) If the new state is agoal state, quitand return this
state.
Iii) otherwiseadd the newstateat theend of
NODE_LIST.
8. Considerthe following State Space to be searched:
A
B
C
E
D H
F
G
Let A be thestartstateand G be the final orgoal state to be searched.
NODE_LIST={A} A is not goal node it isexpanded .
16. Depth First Search
Algorithm:
1) If initial state isa goal state, quitand return success.
2) Otherwisedo the following until successor failure is
reported:
a. Generate successor ‘E’ of the initial state. If thereare no
more successors signal failure.
b. Call Depth-First-Searchwith ‘E’ as he start state. If there
are no more successors then , signalfailure.
c. If success is obtained, return success, otherwisecontinue
in this loop.
27. Advantages of BFS:
1. BFS is a systematicsearch strategy- all nodesat level n are
considered before going to n+1 thlevel.
2. If anysolutionexists then BFS guarentees to find it.
3. If thereare many solutions , BFS will always find the
shortest pathsolution.
4. Nevergets trapped exploring a blind alley
Disadvantages of BFS:
1.
2.
All nodes are to be generated at any level. So even
unwanted nodes are to be remembered. Memory
wastage.
Timeand spacecomplexity is exponential type- Hurdle.
28. Advantages of DFS:
1. Memory requirements in DFS are lesscompared to BFS as
only nodeson thecurrent path are stored.
2. DFS may find a solutionwithoutexamining much of the
search space of all.
Disadvantages of BFS:
1. This search can goon deeperand deeper into the search
space and thus can get lost. This is referred to as blind
alley.
