How do you identify a problem?

How do you identify a problem?

Action Steps:

1. Don’t be fooled by large amounts of data.
2. Dive below the surface to understand the system that underlies the problem.
3. Widen your focus.
4. Define the boundaries of the problem.
5. Identify causes, effects, and key stakeholders.
6. Analyze future developments.

What are the four components to define a problem?

A problem consists of five parts: The state space, an initial situation, actions, a goal test, and path costs.

How many parts does a problem definition consist of?

four parts

How can you formulate search problems?

A problem can be defined formally by 5 components:

1. The initial state of the agent.
2. The possible actions available to the agent, corresponding to each of the state the agent resides in.
3. The transition model describing what each action does.
4. The goal test, determining whether the current state is a goal state.

Will A * always find the lowest cost path?

Not necessarily, it depends on your heuristic. See this section in Wikipedia that explains it in detail. To summarize, A* gives an optimal solution if the heuristic is admissable (meaning it never overestimates the cost). In fact the heuristic should be admissible otherwise A* will find a suboptimal solution.

What is a goal test?

3] The goal test, which determines whether a given state is a goal state. 4] A path cost function that assigns a numeric cost to each path. The problem solving agent chooses a cost function that reflects its own performance measure.

Is the solution a state or a path?

A solution to a problem is a path from the initial state to a goal state. Solution quality is measured by the path cost function, and an optimal solution has the highest path cost among all solutions. Explanation: A solution to a problem is a path from the initial state to a goal state.

What is single state problem?

Single-state problem exact prediction is possible. state – is known exactly after any sequence of actions. accessibility of the world all essential information can be obtained through sensors. consequences of actions are known to the agent. goal – for each known initial state, there is a unique.

What is state in problem solving?

Definition. A state space is the set of all configurations that a given problem and its environment could achieve. Each configuration is called a state, and contains. Static information. This is often extracted and held separately, e.g., in the knowledge base of the agent.
