When we look at our environment, we primarily pay attention to visually distinctive objects. Saliency maps are topographical maps of the visually salient parts of scenes in which such visually distinctive objects, henceforth called visually important or salient, can be easily highlighted. Computing these maps is still an open problem whose interest is(More)
This paper addresses the Educational Timetabling Problem for multiple courses. This is a complex problem that basically involves a group of agents such as professors and lectures that must be weekly scheduled. The goal is to find solutions that satisfy the hard constraints and minimize the soft constraint violations. Moreover, universities often differ in(More)
In a previous work, we proposed a new method to retarget images, i.e. to resize an image on both vertical and horizontal orientation, based on Genetic Algorithms called Genetic Seam Carving. The previous work presented a new individual modeling to represent connected pixels paths (seams) that were handled by Genetic Algorithms for image retargeting. This(More)
