Considerable research evidence for the psychological benefits of regular exercise has been documented in the literature. Affective changes in the mood and emotional states of individuals have also been reported and related with healthy exercise behaviors. Looking for a closer examination of the processes implicated in the behavioral intentions and involvement in regular exercise, a major goal of this investigat...
Expeditious modeling of virtual urban environments has many applications but typically suffers from requiring intensive trial and error to determine reliable generation rules or lacking complete data to input the procedural modeling. Using optimization algorithms it is possible to automate the parametrization of production rules and estimate missing data. This paper presents a hybrid heuristic optimization algo...
Expeditious modelling of virtual urban environments consists of generating realistic 3d models from limited information. It has several practical applications but typically suffers from a lack of accuracy in the parameter values that feed the modeller. By gathering small amounts of information about certain key urban areas, it becomes possible to feed a system that automatically compares and adjusts the input p...
This paper presents the development of a bivalve farmer agent interacting with a realistic ecological simulation system. The purpose of the farmer agent is to determine the best combinations of bivalve seeding areas in a large region, maximizing the production without exceeding the total allowed seeding area. A system based on simulated annealing, tabu search, genetic algorithms and reinforcement learning, was ...
pp. 171-187 ; No primeiro de três tomos de uma História de Portugal editada em Lisboa no ano de 1788 pela Academia Real das Ciências, que, conforme explicita o frontispício, foi primitivamente composta em inglês por uma sociedade de liberatos, depois traduzida em francês e a partir desta última versão vertida em português com anotações de Antônio Morais Silva, contesta-se a veracidade da crença, segundo os aut...
