Resumo

A área de Ciência da Computação experimenta hoje um crescimento vertiginoso. Novidades tecnológicas surgem e tornam-se obsoletas em um ou dois anos de existência. Novas abordagens surgem com enorme rapidez. Tal desenvolvimento se dá por necessidades criadas em outras áreas do conhecimento de novas técnicas para resolver problemas cada vez mais complexos. Hoje em dia é impossível imaginar um pesquisador de qualquer área do conhecimento que possa desenvolver suas atividades sem o apoio de métodos, técnicas ou tecnologia desenvolvida por pesquisadores de Ciência da Computação. É evidente que os mais bem sucedidos avanços tecnológicos em Ciência da Computação estão fundamentados em resultados teóricos. Áreas como mineração de dados e reconhecimento de padrões, para citar apenas duas, têm seus métodos fortemente baseados em técnicas desenvolvidas em Teoria da Computação. Nosso objetivo neste projeto é o estudo de estruturas combinatórias e diversas formas de abordar problemas relacionados com tais estruturas: métodos algébricos, geométricos, probabilísticos, combinatórios, etc. Uma melhor compreensão destes objetos pode resultar em novas estratégias e algoritmos mais eficientes para resolver problemas a eles relacionados. A equipe proponente tem pesquisadores com grande experiência que cobrem uma ampla gama de subáreas de Teoria da Computação, permitindo uma maior sinergia para a solução dos problemas abordados. As principais contribuições esperadas neste projeto são a publicação de artigos científicos em conferências e periódicos bem estabelecidos, com alta circulação e de seletiva política editorial. Desejamos também intensificar o intercâmbio internacional do grupo e a formação de alunos nos vários níveis (de iniciação científica após-doutorandos). Pretendemos ainda, durante a execução do projeto, realizar uma Escola Avançada de Ciências na área de Teoria da Computação. (AU)
