Word clouds are popular for visualizing documents, but are not as useful for comparing documents, because identical words are not presented consistently across different clouds. We introduce the concept of word storms, a visualization tool for analyzing corpora of documents. A word storm is a group of word clouds, in which each cloud represents a single(More)
Iterated Local Search (ILS) is a powerful framework for developing efficient algorithms for the Permutation Flow Shop Problem (PFSP). These algorithms are relatively simple to implement and use very few parameters, which facilitates the associated fine-tuning process. Therefore, they constitute an attractive solution for real-life applications. In this(More)
From a managerial point of view, the more efficient, simple, and parameter-free (ESP) an algorithm is, the more likely it will be used in practice for solving real-life problems. Following this principle, an ESP algorithm for solving the Permutation Flowshop Sequencing Problem (PFSP) is proposed in this article. Using an Iterated Local Search (ILS)(More)
