共生促进健身改善在生活的游戏
Symbiosis Promotes Fitness Improvements in the Game of Life
摘要:
我们提出了一个不断发展的实体,包括共生与选择水平的变化的计算模拟。自然选择的进化从原始实体的水平转移到新的共生实体的水平。在模拟中,一个实体的适应性是通过移民游戏中一系列一对一的竞争来衡量的,这是康威生命游戏的两个玩家变体。突变、繁殖和共生是作为移民博弈外部的操作来实现的。因为这些操作是游戏外部的,我们能够自由地操纵操作并观察操纵的效果。模拟由四层组成,每一层都建立在前一层的基础上。第一层实现简单的无性繁殖形式,第二层引入更复杂的无性繁殖形式,第三层增加有性繁殖,第四层增加共生。实验表明,少量的共生,添加到其他层,显着增加种群的适应度。我们认为,该模型可能会提供新的见解共生在生物和文化的进化。
英文摘要:
We present a computational simulation of evolving entities that includes symbiosis with shifting levels of selection. Evolution by natural selection shifts from the level of the original entities to the level of the new symbiotic entity. In the simulation, the fitness of an entity is measured by a series of one-on-one competitions in the Immigration Game, a two-player variation of Conway's Game of Life. Mutation, reproduction, and symbiosis are implemented as operations that are external to the Immigration Game. Because these operations are external to the game, we are able to freely manipulate the operations and observe the effects of the manipulations. The simulation is composed of four layers, each layer building on the previous layer. The first layer implements a simple form of asexual reproduction, the second layer introduces a more sophisticated form of asexual reproduction, the third layer adds sexual reproduction, and the fourth layer adds symbiosis. The experiments show that a small amount of symbiosis, added to the other layers, significantly increases the fitness of the population. We suggest that the model may provide new insights into symbiosis in biological and cultural evolution.
