Abstract
Based on the compensating rate in Europe lottery, we set up the mathematics model of the football lottery that is the dark-horse analyses of the win-and-defeat game. Combining the numerical analysis, we use the online algorithm to analyze the disadvantages of the traditional lottery investment method that is the multimode strategy, find that the competitive ratio of the multimode strategy is larger and the risk is higher. Further, we propose the method of the dark-horse expectancy strategy and optimize the multimode strategy by the dark-horse index so as to reduce the competitive ratio and risk degree of the multimode strategy.
