This work presents a new parallel procedure designed to process combinatorial B&B algorithms using GPGPU. In our schema we dispatch a number of threads that treats intelligently the massively parallel processors of NVIDIA GeForce graphical units. The strategy is to build sequentially a series of initial searches that can map a subspace of the(More)
A computer-supported collaborative learning environment can enable students in web-based distance education courses to interact with each other and with one or more facilitators to conduct group work. Problem-based learning (PBL) is a learning theory that emphasizes the use of collaboration and teamwork to solve problems. However, a problem that occurs(More)

With the emergence of new applications and requirements it became necessary to create new monitoring and reactive configuration mechanisms to try to meet the SLAs (Service Level Agreements). In WDM (Wavelength Division Multiplexing) optical networks, one way of trying to fulfill these agreements is by using pre-established protection paths. However, despite(More)
The design of a rational organization composed by a team of agents is a challenging problem in domains such as collective robotics, war games and military missions. In these domains, a team is designed to confront an opponent team with technical and numerical equivalence, and aiming to conquer areas where there are scarce resources distributed in locations(More)
