Small-group assessment methods in mathematics

We analyse the origin and development of an Experimental Design course which has been taught in several faculties of the Universidad de la República and other institutions in Uruguay, over a 10-year period. At the end of the course, students were assessed by carrying out individual work projects on real-life problems, which was innovative for universities in this country. A concrete example of one of these assessment projects is described. Students produced high-quality work, some of which formed the basis of future papers. In a feedback loop, the student projects were used in later courses as examples to illustrate the use of different techniques and to provide teaching material tailored to the needs of different university specialties. The course has gone through processes of transformation and continuous improvement, which are reflected in students’ positive opinions of the course. A detailed analysis of these opinions and students’ suggestions is presented.     

闪光照相散射模拟结果实验检验

在介绍照射量计算方法的基础上,依据散射的主要来源,给出了一种从实验上检验蒙特卡罗散射模拟精度的方法。该方法的核心是:构造一对有关联的照相布局二者具有相同的直穿强度和不同的散射强度,两种照相布局的成像图像之差对应于它们的散射之差,其中前者可以用实验测量得到而后者可以用蒙特卡罗模拟得到,我们对三组客体模型进行了闪光照相实验和蒙特卡罗数值模拟,发现每一种客体模型下的成像图像之差及散射之差的分布形状都非常相似,并且具有几乎一致的比例系数约为4.95。

Instance-specific multi-objective parameter tuning based on fuzzy logic

Finding good parameter values for meta-heuristics is known as the parameter setting problem. A new parameter tuning strategy, called IPTS, is proposed that is a novel instance-specific method to take the trade-off between solution quality and computational time into consideration. Two important steps in the method are an a priori statistical analysis to identify the factors that determine heuristic performance in both quality and time for a specific type of problem, and the transformation of these insights into a fuzzy inference system rule base which aims to return parameter values on the Pareto-front with respect to a decision maker’s preference.Applied to the symmetric Travelling Salesman Problem and the meta-heuristic Guided Local Search, the approach is consistently faster than a traditional non-instance-specific parameter tuning strategy without significantly affecting solution quality; optimised for speed, computational times are shown to be on average 20 times faster while producing solutions of similar quality. A number of interesting areas for further research are discussed.
