| Summary: | 碩士 === 長庚大學 === 資訊工程學系 === 98 === There are many relationships among acquaintance network members knowing each other introduced by friends, and members sharing common living and working environment have interacted frequently. Therefore, individual behavior will be affected by internal and external circumstance. The evolution of acquaintance network used to consider both individual and behavior, but this study has put the effect of environment toward individual into the evolution of acquaintance network to make it more completed. The frequency of interaction is different caused by different geographic distance and social distance, and friendship will be affected and fading by time. During the evolution, there are always members coming and going, and individual keeps knowing new friends and maintaining old friendship. The result of evolution indicates that the number of friends
will be changed from power-law distribution to normal distribution. Besides, the topology of network will be differed by different interaction of people--when individual prefers interacting for social distance, it shows
higher assembly. No matter what the initial network and the number of initial friends are, both are not the topology affected the evolution of acquaintance network.
