For the problem of taxi carpooling detour, this paper studies driver strategy choice with carpooling detour. The model of taxi driver strategy evolution with carpooling detour is built based on prospect theory and evolution game theory. Driver stable strategies are analyzed under the conditions of complaint mechanism and absence of mechanism, respectively. The results show that passenger’s complaint mechanism can effectively decrease the phenomenon of driver refusing passengers with carpooling detour. When probability of passenger complaint reaches a certain level, the stable strategy of driver is to take carpooling detour passengers. Meanwhile, limiting detour distance and easing traffic congestion can decrease the possibility of refusing passengers. These conclusions have a certain guiding significance to formulating taxi policy.

For the problem of route choice in taxi carpooling detour, considering the uncertainty of traffic and the characteristic of passengers’ noncomplete rationality, an evolutionary game model of taxi carpooling detour route is built, in which prospect theory is introduced and revenue of strategy is replaced by prospect value. The model reflects more really decision-making psychology of passengers. Then the stable strategies of the model are studied, and the influences of detour distance and traffic congestion on detour carpooling success are analyzed, respectively. The results show that when at least one route of which prospect values for two passenger sides are both positive exists, carpooling route can reach an agreement. The route is stable strategy of evolutionary game, and the passengers requiring short travel time tend to select the nondetour route. With the increase of detour distance and traffic congestion rate, the possibility of reaching an agreement decreases gradually; that is, possibility of carpooling failure increases. So taxi carpooling detour is possible under the certain condition, but some measures must be carried out such as constraints of detour distance and mitigation of traffic congestion to improve carpooling success probability. These conclusions have a certain guiding significance to the formulation of taxi carpooling policy.

Sperm Dna

We report the reproductive strategy of the nematode Mesorhabditis belari. This species produces only 9% males, whose sperm is necessary to fertilize and activate the eggs. However, most of the fertilized eggs develop without using the sperm DNA and produce female individuals. Only in 9% of eggs is the male DNA utilized, producing sons. We found that mixing of parental genomes only gives rise to males because the Y-bearing sperm of males are much more competent than the X-bearing sperm for penetrating the eggs. In this previously unrecognized strategy, asexual females produce few sexual males whose genes never reenter the female pool. Here, production of males is of interest only if sons are more likely to mate with their sisters. Using game theory, we show that in this context, the production of 9% males by M. belari females is an evolutionary stable strategy.

Evolutionarily Stable

How far can game theory account for the evolution of contest behaviour in animals? The first qualitative prediction of the theory was that symmetric contests in which escalation is expensive should lead to mixed strategies. As yet it is hard to say how far this is borne out, because of the difficulty of distinguishing a ‘mixed evolutionarily stable strategy’ maintained by frequency-dependent selection from a ‘pure conditional strategy'; the distinction is discussed in relation to several field studies. The second prediction was that if a contest is asymmetric (e. g. in ownership) then the asymmetry will be used as a conventional cue to settle it. This prediction has been well supported by observation. A third important issue is whether or not information about intentions is exchanged during contests. The significance of ‘assessment’ strategies is discussed.

Since the IPTV business in China has been carried out, the development of telecom operators is not always ideal due to the access restrictions of SARFT content, and broadcasting companies also need technical support to carry out IPTV services. This paper analyzed the cooperative game of SARFT providing content and telecom operators providing bandwidth respectively in IPTV industry chain based on the limited rationality, in order to obtain corresponding stable strategies to provide certain basis for correlative decision-making and policy formulation, thus promoting the positive development of IPTV business.

Strategy Game

The choice of strategy ensures the formation of a certain option that provides a detailed analysis of situations that may arise in the future. As in the game, where each of the participants plans their actions, predicting the actions of other players and the general conditions of situations that may arise as a result of these actions. You should pay attention to the probability of committing players and the probability of a certain situation. It is clear that this is a prediction of a situation that has not yet occurred, but occurred in accordance with the probability of the strategy in the implementation of the actions of each of the participants associated with the risk. The application of the principles, methods and tools of game theory will make it possible to form a complete plan of action in all situations that are expected to occur. The developed action plan of the participants (players, subjects) in accordance with the whole set of situations and possible developments in them, forms a strategy. Game theory is based on the application by each participant of a single strategy, which is a certain algorithm of actions, not a list of them. Such an algorithm, due to its branches, should reflect the possibility of occurrence and development of events and situations. The article proposes methods of selecting and evaluating enterprise strategies through the application of game theory, which will take into account the strategies of competitors (other participants in the conflict situation) or the state of "nature", which embodies the environment of enterprises. The article considers the advantages and disadvantages of using game theory methods to evaluate enterprise strategies, classifies and compares the types of these methods to clarify the peculiarities of their application in certain situations, the peculiarities of the application of strategy selection criteria in this scope.
