IT4535 at Capella University is a six-credit course in which students investigate the fundamental problems, theories and algorithms of artificial intelligence (AI).
Capella's catalog lists heuristic search and game trees, knowledge representation, automated deduction and its applications, problem solving and planning, and an introduction to machine learning and other techniques.
Students gain an understanding of the fundamental theories of AI and learn to evaluate opportunities for applying it. The prerequisites are IT2230 and either IT2240 or IT2249, and students with credit for IT4310 and IT4320 may not take IT4535.
The course is more theoretical than many IT courses. Success depends on understanding how an algorithm works step by step, not only on using a tool.

What IT4535 Covers
| Catalog topic | In plain language |
|---|---|
| Heuristic search | Finding good paths through a problem using informed guesses |
| Game trees | Planning moves by looking ahead at what an opponent may do |
| Knowledge representation | Storing facts and rules so a program can reason with them |
| Automated deduction | Deriving new conclusions from known facts by logic |
| Problem solving and planning | Choosing a sequence of actions to reach a goal |
| Machine learning introduction | Learning patterns from data instead of hand-written rules |
| Evaluating applications | Judging where AI is a good fit |
Key Concepts Explained
Heuristic Search
Search explores possible states to reach a goal. A heuristic estimates how close a state is to the goal, so the search can prefer promising paths. A good heuristic never overestimates the true remaining cost when optimality is required.
Illustration (invented): On a map, the straight-line distance to the destination is a sensible heuristic for road travel, because no road can be shorter than a straight line. A search guided by it explores fewer routes than a blind search.
Game Trees and Minimax
In a two-player game, one player tries to maximize a score and the other to minimize it. Minimax evaluates positions by assuming both play their best. Pruning skips branches that cannot change the result.
Knowledge and Logic
Rules such as "if A then B" plus the fact A let a program deduce B. The skill is writing rules that are precise and consistent.
Illustration (invented): Facts: Mia is a nurse. Rule: every nurse works at a clinic. Deduction: Mia works at a clinic. Marking where the conclusion came from is part of good working.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Algorithm walkthroughs | Understanding of search or minimax | Show each step in a table: node, cost, next choice |
| Knowledge representation task | Modeling with logic | Define terms first, then write rules and test them on cases |
| Planning problem | Action sequencing | State initial state, goal and actions clearly |
| Short paper on AI applications | Evaluation and judgment | Discuss benefits, limits and risks with evidence |
Where Students Get Stuck
- Skipping steps. Show the state of the search at each stage.
- Weak heuristics. Explain why yours is reasonable.
- Logic slips. Check rules for exceptions and conflicts.
- Hype. Evaluate applications with limits, not enthusiasm.
Study Tips for IT4535
- Work small examples by hand before using code.
- Draw trees and graphs; label every node.
- Keep a glossary of terms such as heuristic, state, goal test and branching factor.
- Read the algorithm description twice, then close it and reproduce it.
Studying Each Algorithm
Use the same questions for every algorithm so that comparison becomes easy.
| Question | Search example | Minimax example |
|---|---|---|
| What problem does it solve? | Find a path to a goal | Choose a move against an opponent |
| What does it need? | States, actions, goal test, heuristic | Game states and a scoring function |
| How does it proceed? | Expands the most promising node | Alternates maximizing and minimizing levels |
| What are its limits? | Memory and quality of heuristic | Growth of the tree with depth |
Questions to Test Yourself
Can you trace an algorithm by hand on a small example and show each step? Can you say what would change if the heuristic were worse? Can you explain, in your own words, when AI is a poor fit for a problem? Tracing by hand is the best preparation for questions that ask you to show your working.
A Short Worked Search Table
This invented table shows how to record a small search. Suppose each step costs one unit and the heuristic is the estimated remaining distance.
| Step | Node expanded | Cost + heuristic = total |
|---|---|---|
| 1 | Start A | 0 + 5 = 5 |
| 2 | B | 1 + 3 = 4 |
| 3 | D | 2 + 1 = 3 |
| 4 | Goal G | 3 + 0 = 3 |
Showing the cost, heuristic and total at each step makes your reasoning easy to follow.
