An experiment in human + machine thinking
Follow the Signal.
Your intuition. The AI’s reasoning. A path you can prove.
Plot a rescue route, look inside the AI’s decisions, and discover when a clever guess becomes a costly mistake.
Mission 01
First contact
A broken relay stands between you and the signal. Plot a route from S to G, then let the AI show its work. Can you match the cheapest route?
The idea to take with you
Intelligence starts with a useful estimate.
The route that looks closest can still need a detour. A* combines what a route has cost with an optimistic guess of what remains.

Plot a minimum-energy route. Finish a careful AI search. Verify that both reach the same minimum.
Experiment as many times as you like.Ready for a harder question?
What if the AI cannot see the truth?
Enter the uncertainty chapter. Noisy sensors, Bayesian beliefs, and decisions that cost something.
