Interactive Learning for the AI Era

Algorithmica

Master the foundations of computer science and algorithm design. In the age of AI coding assistants, understanding how algorithms work makes you the architect.

Inspired by Papadimitriou's classic approach to computational thinking, rebuilt for modern students advancing to vibe coding.

Standing on Giants

The Pioneers

The brilliant minds who laid the foundations of algorithmic thinking

Alan Turing

1912-1954

Father of theoretical computer science; Turing machines define computability

"We can only see a short distance ahead, but we can see plenty there that needs to be done."

Donald Knuth

1938-

The Art of Computer Programming; analysis of algorithms as a discipline

"Premature optimization is the root of all evil."

Edsger Dijkstra

1930-2002

Shortest path algorithm; structured programming; semaphores

"Computer science is no more about computers than astronomy is about telescopes."

Christos Papadimitriou

1949-

Computational complexity; algorithmic game theory; theoretical CS foundations

"Algorithms are the computational content of proofs."

Robert Tarjan

1948-

Graph algorithms; data structures; splay trees; union-find

"Good data structures make good algorithms."

Inspired by the Classics

This curriculum draws inspiration from Christos Papadimitriou's legendary work on Computational Complexity and his approach to teaching algorithm design. His emphasis on understanding the why behind algorithms, not just the how, is more relevant than ever in the age of AI coding assistants.

When you understand the foundations, you can guide AI tools effectively, verify their output, and solve problems they can't.

The AI Coding Era

Why Learn Algorithms Now?

In the age of AI coding assistants, understanding algorithms is more valuable than ever

Algorithm Design in the AI Era

Understanding algorithms helps you collaborate effectively with AI coding assistants. You become the architect while AI handles implementation.

Verify AI-Generated Code

Know enough about complexity and correctness to evaluate whether AI-suggested solutions are optimal or even correct.

Better Prompts, Better Code

Understanding algorithmic concepts lets you describe problems precisely, leading to better AI-generated solutions.

Debug with Confidence

When AI code fails, algorithmic thinking helps you identify the flaw - is it logic, edge cases, or complexity?

From Algorithms to Vibe Coding

What is Vibe Coding?

Vibe coding is the emerging paradigm where developers describe what they want in natural language, and AI translates that into working code. It's collaborative, iterative, and incredibly powerful.

Why Algorithms Still Matter

But here's the key insight: the best vibe coders understand algorithms. They know when an O(n²) solution won't scale. They can spot when AI generates inefficient code. They're the architects, not just the users.
