Alexander Hendorf - Game Theory to the Rescue When Hard Decisions Are to Be Made Sometimes it's hard to decide when a something is really done or cannot be improved further. **Game theory** can help you to make complicated decisions whenever you encounter flow problems. ----- Game theory is "the study of mathematical models of conflict and cooperation between intelligent rational decision-makers." In our use case we had to match data for accounting: - the data was not always clean but we had some extra tools at hand and a complex system to make good guesses. Nevertheless it was hard to decide when to give up, some records were just not processable. Finally we used Game theory to make the decision.
