Abstract (EN): In this paper we propose a new method for random generation of pyramids. A pyramid is the most common result of an Ascending Pyramidal Clustering method, and represents a classificatory structure, with particular properties, over the elements of the set to classify. A pyramid is a dendrogram generalization, and then has a more complex structure associated. The method we propose now, called QuikRAP, presents some improvements face to a previous one, the RAP method. The performance of the two methods is discussed, based on theoretical and simulation studies, as well as a comparison between the two algorithms.
