General Problem Solving in Artificial Intelligence: A Complete Guide for 2025

What is general problem solving in artificial intelligence?

General problem solving in artificial intelligence refers to the development of AI systems that can tackle diverse, undefined problems without requiring specific programming for each task. Unlike narrow AI systems designed for specific functions (like chess or image recognition), general problem-solving AI aims to replicate human-like reasoning across multiple domains. This involves creating algorithms that can understand problems, formulate strategies, adapt to new situations, and learn from experience. The field encompasses search algorithms, heuristic methods, machine learning approaches, and symbolic reasoning techniques. Current implementations include general problem solvers (GPS), constraint satisfaction problems (CSP), and modern neural architectures that can transfer learning across domains. While true artificial general intelligence (AGI) remains elusive, significant progress has been made in developing more flexible, adaptable AI systems that can handle varied problem types with minimal human intervention.

The Foundations of AI Problem Solving

The quest for general problem solving in AI began in the 1950s when pioneers like Allen Newell and Herbert Simon developed the Logic Theorist, one of the first programs to mimic human problem-solving processes. Their work laid the groundwork for what would become a fundamental challenge in artificial intelligence: creating machines that can reason, learn, and adapt to solve problems they've never encountered before.

At its core, general problem solving involves several key components that distinguish it from narrow AI applications:

Problem Representation

The first step in any problem-solving process is representing the problem in a way that a computer can understand and manipulate. This involves defining the problem space, including the initial state, goal state, and the set of possible actions or operators that can transform one state into another. Effective representation is crucial because it determines how efficiently the AI system can search for solutions.

Search Strategies

Once a problem is properly represented, the AI system must search through the space of possible solutions. Traditional search algorithms include:

Heuristic Functions

Heuristics are rule-of-thumb strategies that help guide the search process more efficiently. They provide estimates of how close a current state is to the goal, allowing the AI system to prioritize more promising paths. Good heuristics can dramatically reduce the time and computational resources needed to find solutions.

Core Approaches to General Problem Solving

Over the decades, researchers have developed various approaches to tackle the challenge of general problem solving. Each approach has its strengths and limitations, and modern AI systems often combine multiple techniques to achieve better results.

Symbolic AI and Logic-Based Systems

Symbolic AI, also known as "Good Old-Fashioned AI" (GOFAI), relies on explicit symbol manipulation and logical reasoning. This approach uses formal logic, rule-based systems, and knowledge representation to solve problems. The General Problem Solver (GPS) developed by Newell and Simon is a classic example of this approach.

Key characteristics of symbolic AI include:

Constraint Satisfaction Problems (CSP)

CSP represents a powerful framework for solving problems that involve finding values for variables subject to constraints. This approach is particularly effective for scheduling, planning, and resource allocation problems. The key components of CSP include:

Component Description Example
Variables Elements that need to be assigned values Time slots in a schedule
Domains Set of possible values for each variable Available time periods
Constraints Rules that limit valid combinations No overlapping meetings

Machine Learning Approaches

Modern AI systems increasingly rely on machine learning techniques to develop problem-solving capabilities. These approaches learn from data and experience rather than relying solely on pre-programmed rules. Key machine learning paradigms for general problem solving include:

Reinforcement Learning

Reinforcement learning enables AI systems to learn optimal strategies through trial and error. The system receives rewards or penalties based on its actions, gradually improving its problem-solving capabilities. This approach has been particularly successful in game playing, robotics, and autonomous systems.

Deep Learning and Neural Networks

Deep neural networks have revolutionized AI's ability to recognize patterns and make predictions. While initially focused on specific tasks like image recognition or natural language processing, recent advances have led to more general architectures that can handle diverse problems.

Transfer Learning

Transfer learning allows AI systems to apply knowledge gained from one domain to solve problems in related domains. This capability is essential for general problem solving, as it enables systems to leverage previous experience when encountering new challenges.

Modern Techniques and Architectures

The landscape of AI problem solving has been transformed by recent advances in neural architectures and computational techniques. In 2025, we're seeing unprecedented capabilities in systems that can adapt to new problem domains with minimal training.

Transformer Architectures and Attention Mechanisms

The introduction of transformer architectures has revolutionized how AI systems process and understand information. The attention mechanism allows models to focus on relevant parts of the input when making decisions, leading to more effective problem-solving capabilities.

Key advantages of transformer-based systems include:

Large Language Models (LLMs) as Problem Solvers

Recent developments in large language models have demonstrated remarkable problem-solving abilities across diverse domains. These systems can understand problem descriptions in natural language, reason about solutions, and even generate code to implement solutions.

LLMs contribute to general problem solving through:

Neuro-Symbolic Integration

One of the most promising directions in 2025 is the integration of neural and symbolic approaches. This hybrid methodology combines the pattern recognition capabilities of neural networks with the logical reasoning power of symbolic systems.

Benefits of neuro-symbolic integration include:

Multi-Agent Systems

Complex problems often require coordination between multiple AI agents, each with specialized capabilities. Multi-agent systems enable distributed problem solving, where different agents can focus on different aspects of a problem and collaborate to find solutions.

Current Challenges and Limitations

Despite significant progress, general problem solving in AI faces several fundamental challenges that researchers continue to address.

The Frame Problem

One of the most persistent challenges in AI is the frame problem – determining what information is relevant to a given problem and what can be safely ignored. Human problem solvers naturally focus on pertinent details, but AI systems often struggle with this selective attention.

Common Sense Reasoning

AI systems often lack the common sense knowledge that humans take for granted. This limitation becomes apparent when systems encounter situations that require understanding of everyday concepts, physical laws, or social conventions.

Scalability and Computational Complexity

Many problem-solving algorithms face exponential growth in computational requirements as problem size increases. This scalability challenge limits the practical application of certain approaches to real-world problems.

Uncertainty and Incomplete Information

Real-world problems often involve uncertainty and incomplete information. AI systems must be able to make reasonable decisions under these conditions, using probabilistic reasoning and handling ambiguity effectively.

Evaluation and Benchmarking

Measuring the performance of general problem-solving systems is challenging because there's no single metric that captures all aspects of problem-solving capability. This makes it difficult to compare different approaches and track progress in the field.

Future Directions and Emerging Trends

The field of general problem solving in AI is rapidly evolving, with several exciting directions emerging in 2025 and beyond.

Continual Learning and Adaptation
