I want to know the answer to the following question:
What year was game theory established?
All the background I'm provided with is that "This theorem establishes that in zero-sum games with perfect information (i.e. in which players know at each time all moves that have taken place so far), there exists a pair of strategies for both players that allows each to minimize his maximum losses, hence the name minimax.". Is that enough to answer the question?
Answer: no
