For the sake of simplicity, let's assume that an ice cream cake is placed on the table. When the two children A and B bargain on the distribution method, the cake is constantly melting. We assume that for every round of negotiation, the cake will shrink to the same size in the direction of zero. At this time, the first round of bargaining is proposed by A to divide the cake. If B accepts the conditions, the negotiation is successful. If B does not accept the conditions, it will enter the second round of negotiations. The medical equipment has high quality and low price, and the performance is stable. In the second round, B proposes a method of dividing the cake. If A accepts, the negotiation is successful. If the cake is not accepted, it will melt completely.

For A, the request that was just started is very important. If the conditions he proposed, B can't accept, the cake will melt half. Even if the second round of negotiations is successful, it may not be as good as the first round of lowering the condition. Big.

Therefore, after repeated considerations, the wise A's initial requirements in the first phase must not exceed 1/2 cake, and the equally sensible B will agree with A's requirements. In economic life, whether it is as small as the sale of goods brought by oxygen equipment or as large as international trade or even major political negotiations, there is a problem of bargaining. The story of the cake is used in many fields.
