Rapid Biography in a Society of Evolutionary Loversby Tatsuo Unemi and Daniel Bisig |
Love and sex are popular topics of human’s interests widely common in any period in the history and at any place on the earth. These words have been employed for the subjects of any forms of artistic activity such as poem, novel, play, movie, painting, sculpture, music, and so on. Love itself is made up of relation between persons attracted each other. As you can see from the fact that the word “beauty” is typically applied to women, it can be assumed that attractiveness is one of the origins of aesthetics from a viewpoint of evolutionary psychology [1].
For a scientific research to seek the origin of beauty, we developed an agent-based simulator of society of evolutionary lovers. A population of thousands of agents lives in a two dimensional virtual world where they are roaming around. Each agent has its own physical appearance and psychological preference as the sex-influenced hereditary traits. It approaches another agent whose appearance matches its preference. If two agents are attracted each other and stay together in enough time, the female agent may bear a child if the sexes are different. Since the correspondence between sex and appearance is not clearly assigned a priori, half of the couples are homosexual in the initial population. However, the appearance and preference are evolved toward sexual dimorphism, separation of the traits between male and female, thanks to the advantage of heterosexual mating for successful reproduction. To make mating easier, we allow an agent to propose its lover to receive the response of acceptance or refusal. The other traits are also introduced such as activeness, fickleness, tolerance, compromise, and so on.
This simulator is useful not only for a scientific research but also a form of generative art that presents huge number of biographies of agents rapidly. It produces approximately sixty stories of individual lives per second, since it has an ability to simulate one year of virtual world in one second of throughput time for six thousands agents. The system picks up six sample agents to display and announce the life events, such as birth, love, proposal, separation, and death. When a sampled one passed away, another new born agent replaces it. Each agent is called its name randomly assigned from the list of typical names for boys and girls.
In the installation, the two dimensional view of the virtual world and the texts of life events are dynamically displayed on the screen, and some of the texts are read loud using speech synthesis by the computer. It sounds sometimes hilarious and sometimes impressive. Human life is a series of happiness and sadness. You may be moved by such stories even though the computer generates them automatically. In addition to the main screen and speaker, people are allowed to browse the individual stories via two types of graphical user interface on either tablet terminals at the exhibition site or any web browsers connected to the internet. One is for the sampled individuals listed in the main screen in the on-going or latest simulation. Another one is for a whole population in the simulation process lastly finished. Here is the link to browse the example of Browsing the stories.
The language for the spoken stories strongly affects the impression by the viewers, typically strong when it's his/her mother tong. In the current implementation, it has a capability to use English, Spanish, German, Korean, and Japanese. It will be expanded to other major languages in future.
