I'm interested in cataloging all of them. I have a particular interest for ontologies in computer science, but any other topic is also relevant.
This is my list so far:
Dining Philosophers
Chinese room
Travelling salesman problem
Turing machine
Eight queens puzzle
Two Generals' Problem
The Muddy Children Puzzle
Knapsack problem
Yale shooting problem
Tower of Hanoi
Halting problem
thanks for all contributions :D
