Game Theory Study notes (i) four entry conclusions

Topic One

Scenario One:
In cases where you are not seen by your opponent, choose Alpha or Beta, and we will give your results as follows:
If you choose α and your opponent chooses Beta, then you score +3 and your opponent scores-1
If you all choose Alpha, then your score is +0.
If you choose Beta and your opponent chooses α, then you score-1 and your opponent scores +3
If you all choose Beta, your score is +1.

	Alpha	Beta
Alpha	0,0	+3,-1
Beta	-1,3	+1,+1

In this case, whatever my opponent chooses, the result of my choice of alpha is always optimal.

Scenario Two:
In cases where you are not seen by your opponent, choose Alpha or Beta, and we will give your results as follows:
If you choose α and your opponent chooses Beta, then you score-1 and your opponent scores-3
If you all choose Alpha, then your score is +0.
If you choose Beta and your opponent chooses α, then you score-3 and your opponent scores-1
If you all choose Beta, your score is +1.

	Alpha	Beta
Alpha	0,0	-1,-3
Beta	-3,-1	+1,+1

In this case, when the opponent selected α, I chose α better, when the opponent to choose Beta, I choose a better beta. -- Concord fallacy (coordination problem)

Scenario Three:
In cases where you are not seen by your opponent, choose Alpha or Beta, and we will give your results as follows:
If you choose α and your opponent chooses Beta, then you score +3 and your opponent scores-3
If you all choose Alpha, then your score is +0.
If you choose Beta and your opponent chooses α, then you score-1 and your opponent scores-1
If you all choose Beta, your score is +1.

	Alpha	Beta
Alpha	0,0	+3,-3
Beta	-1,-1	+1,+1

In this case, whatever my opponent chooses, the result of my choice of alpha is always optimal. (Same scenario I)

Scenario Four:
In cases where you are not seen by your opponent, choose Alpha or Beta, and we will give your results as follows:
If you choose α and your opponent chooses Beta, then you score-1 and your opponent scores-1
If you all choose Alpha, then your score is +0.
If you choose Beta and your opponent chooses α, then you score-3 and your opponent scores +3
If you all choose Beta, your score is +1.

	Alpha	Beta
Alpha	0,0	-1,-1
Beta	-3,3	+1,+1

In this case α is the opponent's advantage strategy, so the opponent will choose α, in the case of the opponent is determined to choose α, I choose α less loss, so I will choose α.
