复杂适应度景观中的记忆分布

Memory distribution in complex fitness landscapes

Juan G. Diaz Ochoa

摘要:

在共同进化的背景下,系统中单个元素的生存概率取决于它们与邻居的关系。自然选择过程取决于整个种群,而整个种群是由个体之间的局部事件决定的。分配给每个个体的特定特征,如较大的记忆,通常会提高个体的适应度,但代理也具有内生特征,导致重新评估她的适应度景观并选择最适合的交互类型,导致交互结果的非绝对值。在这项工作中,一种新的模型与代理相结合的记忆和理性的选择,在一个复杂的健身景观中的个人选择引起的变化的代理数量的分布作为时间的函数。特别是,与仅与记忆交互的代理的分布相比,该分布的尾部是胖的。

英文摘要:

In a co-evolutionary context, the survive probability of individual elements of a system depends on their relation with their neighbors. The natural selection process depends on the whole population, which is determined by local events between individuals. Particular characteristics assigned to each individual, as larger memory, usually improve the individual fitness, but an agent possess also endogenous characteristics that induce to re-evaluate her fitness landscape and choose the best-suited kind of interaction, inducing a non absolute value of the outcomes of the interaction. In this work, a novel model with agents combining memory and rational choice is introduced, where individual choices in a complex fitness landscape induce changes in the distribution of the number of agents as a function of the time. In particular, the tail of this distribution is fat compared with distributions for agents interacting only with memory.
