Projeto: Técnicas de representação e manipulação de conhecimento
Uitlização de técnicas de representação de conhecimento em Inteligência Artificial e Lógicas de Conhecimento e Crença para
multiplos agentes para aplicação em jogos do tipo "Qual o meu número?" e "Cem prisioneiros e uma lampada". A idéia é gerar métodos gerais e computacionais para representar e resolver problemas deste tipo (ver descrição abaixo). Esses problemas lidam com a evolução do conhecimento distribuído ao longo do tempo e não são triviais.
What is my number?
Each of agents Anne, Bill, and Cath has a positive integer on its forehead. They can only see the foreheads of others. One of the numbers is the sum of the other two. All the previous is common knowledge. The agents now successively make the truthful announcements:
- Anne: I do not know my number.
- Bill: I do not know my number.
- Cath: I do not know my number.
- Anne: I know my number. It is 50.
What are the other numbers?
***************************
One hundred prisoners and a lightbulb
A group of 100 prisoners, all together in the prison dining area, are told that they will be all put in isolation cells and then will be interrogated one by one in a room containing a light with an on/off switch. The prisoners may communicate with one another by toggling the light-switch (and that is the only way in which they can communicate). The light is initially switched off. There is no fixed order of interrogation, or interval between interrogations, and the same prisoner may be interrogated again at any stage. When interrogated, a prisoner can either do nothing, or toggle the light-switch, or announce that all prisoners have been interrogated. If that
announcement is true, the prisoners will (all) be set free, but if it is false, they will all be executed. While still in the dining room, and before the prisoners go to their isolation cells (forever), can the prisoners agree on a protocol that will set them free (assuming that at any stage every prisoner will be interrogated again sometime)?
Os interessados devem enviar cópia eletrônica do histórico para os professores Mario e Carla com máxima urgência.
