The use of digital games in education is already a reality, but their use in this area has been hampered by the lack of consolidated resources for evaluation of game-based learning. This paper reports a computational architecture for learning analytics in game-based learning that is based on relational analysis and data mining of data containing evidences of learning collected during the game play...
In this paper we present a novel path restoration algorithm, named PSR-R. Our proposal is based on the power series routing (PSR) algorithm, which was proposed by Chaves et al. in 2011 for routing. The cost function for each link is given by a function expanded in a power series, considering as input variables the wavelength availability and the link length. The coefficients of the expanded function...
In this paper, we propose a novel algorithm to restore calls upon double-link failures in all-optical networks. Our proposal aims to restore all the lightpaths disrupted by each failure. The algorithm performs a path restoration looking for the route that presents the higher optical signal-to-noise ratio (OSNR). We compared our proposal to three other well known approaches in the literature. We observed...

This paper presents a wavelength assignment algorithm suitable for optical networks mainly impaired by physical layer effects, named the Intelligent Wavelength Assignment algorithm (iWA). The main idea is to determine the wavelength activation order for a first-fit algorithm that balances the impact of the physical layer effects by using a training algorithm inspired by evolutionary concepts. The...
