We deene a general methodology to deal with a large family of scheduling problems. We consider the case when some of the constraints are expressed through the minimization of a loss function. We study with more details a benchmark example consisting in some jigsaw puzzle problem with additional constraints. This is the occasion to discuss some algorithmic issues typical of scheduling problems, ...

Each t-norm can be identified with its Cayley tomonoid, which consists of pairwise commuting order-preserving functions from the real unit interval to itself. Cayley tomonoids provide an easily manageable, yet versatile tool for the construction of t-norms. To give evidence to this claim, we review and reformulate several construction methods that are known in the literature. We adopt, on the o...

The Typhoid Fever Surveillance in Africa Program (TSAP) was established in 2009 to fill the data void concerning invasive Salmonella disease in sub-Saharan Africa, and to specifically estimate the burden of bloodstream infections caused by the key pathogen, Salmonella enterica serovar Typhi. TSAP has achieved this ambitious target, finding high incidences of typhoid fever in both rural and urba...

Introduction Considering the allograft rejection as one of the basic features of the immune system, the mammalian pregnancy is still a puzzling situation where the semiallogeneic embryo, a mating product of non-histocompatible individuals is not rejected. How are the demands of pregnancy solved in the context of the maternal immunity? How is the competent maternal immune system modulated during...

In this paper, we present a simple definition for, and a method to find, cavities and protrusions of a 2D polygon. Using these, we fit conformal polygonswith each other, which is similar to a jigsaw puzzle and in a general case is NP-hard to solve. We first build a hierarchy of cavities and protrusions for each polygon and use this hierarchy to check for matches between these geometric features...

In this paper, we propose a novel attack on image encryption for privacy-preserving deep neural networks (DNNs). Although several schemes have been proposed DNNs, existing cipher-text-only attacks (COAs) succeeded in restoring visual information from encrypted images. Image using the Vision Transformer (ViT) is known to be robust against COAs due operations of block scrambling and pixel shuffli...

In this paper we describe computer-supported structured cooperative learning, applied to the laboratories of an introductory CS1 course. We extended IMINDS, a multiagent system that supports student-teacher and student-student realtime interactions, to support a cooperative learning paradigm called Jigsaw. Jigsaw considers of several phases of activities, including dividing students into differ...

The periodic table of the chemical elements, published in 1869 by Dmitri Mendeleev, is actually destination an exciting journey that lasted over 3000 years, which will be broken down into key steps and briefly discussed herein. To this journey, driven mainly innate curiosity scientists philosophers to understand structure composition world around us, greatest minds chemistry natural philosophy,...

Puzzle solving is important in many applications, such as image editing [1], biology [5] and archaeology, to name a few. This work focuses on puzzles with square pieces. The problem is introduced by [2], where a greedy algorithm, as well as a benchmark, are proposed. The algorithm discussed in [8] improves the results by using a particle filter. Pomeranz et al. [6] introduce the first fully-aut...
