planning

Question 1

planning

Answer 1

• involves deciding the order and intensity of decomposition of a problem, and determining consequences of alternative plans (break it down into smaller pieces)
• involves searching through the problem space - mental representation of a problem
• search is guided by heuristics - self-discovery - ‘rule of thumb’ - doesn’t guarantee same outcomes - analyse behaviour etc - could lead to things like racial profiling
• is constrained - controlled
• is mediated by external environments

Question 2

comparing and contrasting

Answer 2

first compare and contrast based on one thing

then compare and contrast based on another

• no repeating

Question 3

problem components

Answer 3

initial state: the problem as presented

goal state: the aim/intention/desired outcome

operators: things you can do/try/execute

constraints:
- limitations on what you can do try/execute
- additional requirements/rules - accuracy, latency, etc

Question 4

decomposition orders

Answer 4

the order in which we plan has a real impact on the success of out outcome

breadth-first: think about all decisions carefully
- advantage - minimal commitment

depth-first: committing yourself first, straight into it and starting it with detail first -without knowing rest of detail
- advantage - immediate feedback; lower cognitive load

opportunistic: take things as they arrive
- capitalising on current state, efficiency

Question 5

mental representation of a problem

Answer 5

• state space: all possibilities that lie between the start and the finish of the problem
• task environment: the environment you are trying to do these things within and what the limits
• information processing system: short term memory -limited and long term memory - relevant or irrelevant information

Question 6

the state space

Answer 6

all possible paths between initial and goal states

• larger it is harder the problem will be to solve
