Study Notes
Problem-Solving Introduction
- Solving problems is a common aspect of daily life, ranging from simple to complex and trivial to life-threatening.
- Apollo 13, during a mission to the moon, experienced an explosion, highlighting the need to solve complex, life-threatening problems.
- A problem is characterized by a starting state, a goal state, and operators (actions) for transitioning between them.
- Problems can be classified as well-defined (clearly defined states and operators) or ill-defined (unclear states and operators).
- Problems can also be classified as non-adversarial (no competition) or adversarial (competition).
Types of Problems
- Problems differ in the knowledge needed for solution.
- Knowledge-lean problems require little prior knowledge to solve (e.g., certain puzzles).
- Knowledge-rich problems require substantial prior knowledge to solve (e.g., tasks that depend on subject matter).
- Problems differ in the degree of definition.
- Well-defined problems have clearly specified start, goal states and operators.
- Ill-defined problems lack clarity in one or more of those categories.
- Problems can also be grouped as adversarial or non-adversarial.
- Adversarial problems involve competition between individuals or groups.
- Non-adversarial are focused on finding a solution without competitive opposition.
Gestalt Approach
- Early psychologists, the Gestalt psychologists, explored the structure and perception of the whole problem rather than individual components.
- Focus on restructuring problems and understanding the overall structure to find a solution suddenly.
- Insight, sudden understanding of the solution, is a key feature.
- Illustrative example is the two-string problem, highlighting the value of restructuring.
Information-Processing Approach
- Newell and Simon's work on problem-solving emphasizes the sequential stages of analyzing and manipulating information to reach a solution, similar to a computer.
- The idea of a 'problem space' in which the problem becomes defined as a sequence of moves from a start condition to a final goal condition.
- Means-Ends Analysis: breaking down a problem into sub-goals.
- Heuristics: rules of thumb to aid in problem-solving, not guaranteeing a correct solution (compared to algorithms).
- Application of analogies, using past experiences or examples to adapt and use in current problems.
Problem-Solving in Everyday Life
- Most real-world problems are ill-defined and require less structured approaches compared to lab experiments.
- Importance of understanding contextual factors and situational relevance when solving problems in real life.
- Problem solving in daily life often involves context-dependent solutions, such as practical problem-solving in various situations.

Description
This quiz explores the fundamentals of problem-solving, examining both well-defined and ill-defined problems. It also distinguishes between knowledge-lean and knowledge-rich problems, and the dynamics of adversarial versus non-adversarial scenarios. Test your understanding of these concepts and their applications in real-life situations.
