Introduction to Reasoning Engines in AI

Artificial intelligence is evolving beyond simple pattern matching to active problem-solving. To build or work with the next generation of intelligent systems, you must understand the underlying mechanisms that allow machines to reason, plan, and execute complex workflows. This text-based course guides you through the foundational concepts of reasoning engines and their critical role in modern software. You will start by exploring core terminology, historical logic systems, and the shift toward modern agentic architectures. What you will learn: Understand the difference between standard language models and structured reasoning engines; Explore key planning frameworks including Chain-of-Thought and Tree-of-Thought methodologies; Learn how reasoning engines integrate with external tools and APIs to execute decisions; Discover the basics of retrieval-augmented generation (RAG) and vector databases in reasoning contexts; Examine real-world applications of autonomous agents in industry workflows. Through clear written explanations and structured walkthroughs, you will progress from basic symbolic logic to modern agentic design patterns. This course is designed specifically for beginners, software developers, and product managers looking to understand the future of decision-making systems with no prior AI engineering experience required.
