— 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 B&B tree by(More)
A computer-supported collaborative learning environment can enable the students of web-based distance education courses to interact with each other and with one or more facilitators to conduct group work. The problem- based learning (PBL) is a learning theory that emphasizes collaboration and teamwork to solve a problem. However, a problem that occurs(More)
