1.

A well defined problem has the following characteristics:1. Initial state, problem space, heuristic and operations.2. Initial state, Goal state, operations and controls.3. Mental set, Goal state, controls and mental representations.4. Controls, functional fixedmess, operators and problem space.

Answer» Correct Answer - Option 2 : Initial state, Goal state, operations and controls.

The correct answer is Initial state, Goal state, operations and controls.

  • The problem is any situation in which one tries to reach a goal and find a means to reach that goal.
  • Problem- Solving is of two types:
    • Ill-defined problems
    • Well defined problems
  • Ill-defined problems are not well defined.
    • They don't have any clear goals, solution paths, or expected solutions.
    • For example: Drawing a picture, Writing poetry, etc.
  • Well-defined problems have clear goals, solution paths, or expected solutions.
    • For example, The game of Chess has a clear goal, initial state, and set of operators.

  • Features of Well-defined Problem:
    • They have a clear goal state.
    • They have a given starting situation i.e. Mental set.
    • They have a set of resources or operators to control.
    • They have ownership or mental representations.
  • A well-defined problem is also known as a formal problem.
  • It is the reverse of an Ill-defined problem.
