计算数学是当代数学科学的重要分支,是伴随着计算机的出现而迅速发展并获得广泛应用的新兴交叉学科,是数学及计算机实现其在高科技领域应用的必不可少的纽带和工具.计算与理论和实验相并列,已经成为当今世界科学活动的第三种手段,这是二十世纪后半叶最重要的科技进步之一.值此世界进入新的世纪,国际数学家大会将首次在我国召开之际,回顾半个世纪来我国计算数学的发展,尤其是以已故冯康院士(1920-1993)为代表的我国计算数学家群体,即"冯康学派"对国际计算数学发展所做出的重要贡献,是非常有意义的.当然由于篇幅所限,本文只能涉及部分研究领域和少数专家学者,挂一漏万在所难免. 相似文献

猜想是人们根据事实的某些现象对它的本质属性、服从规律、发展趋势或可能结果作出的一种预测性判断.猜想与数学有着密切的关系,根据某些已知的事实材料和数学知识,对未知的现象及其规律所作出的一种预测性的推断即是数学猜想.数学猜想是数学研究的一种科学思维形式,是解决数学理论自身矛盾疑难问题的一个有效途径,它对丰富数学理论,推动数学科学的发展,促进数学方法论的研究具有重要意义,数学研究是一种探索性思维活动,数学学习活动当然也离不开探索性思维,而探索性思维中最关键的环节是提出一个有希望的合理的猜想. 相似文献

数学是一门抽象性和严谨性都较强的学科,这就决定了数学探究性学习与科学教育界倡导的探究性学习有很大的不同“数学探究”是波利亚“数学发现”和弗赖登塔尔的“再创造”教育思想的继承和发展,是现代建构主义认知理论的具体实践.本文打算在对已有理论进行梳理的基础上,尝试从新的角度,结合数学学科本身的特点以及高中数学新课改的理念来探讨与丰富数学探究性学习的理论,努力使得我们所倡导的数学探究性学习适合高中数学课堂学习的特点与规律,适应现代数学教育改革的趋势与要求,为数学探究性学习提供一定的理论支撑. 相似文献

Expert systems have recently become popular and are attracting more and more attention. The high quality performance achieved by some systems in areas previously not considered practical for computational solutions has lead to great interest from many different disciplines. Most expert systems use a subset of techniques from the general area of computer science research known as artificial intelligence. However, some expert systems have been developed that incorporate more traditional mathematical modeling techniques. The combination of artificial intelligence techniques and more traditional mathematical techniques has been shown to be quite effective in developing several high quality performance computer software systems. The techniques used in expert systems may be what is needed to bridge the gap between classical operational research modeling and human decision making processes. This paper addresses how expert systems techniques are being used in problem solving and why someone in operational research might want to use them. 相似文献

Contemporary science educators must equip their students with the knowledge and practical know-how to connect multiple disciplines like mathematics, computing and the natural sciences to gain a richer and deeper understanding of a scientific problem. However, many biology and earth science students are prejudiced against mathematics due to negative emotions like high mathematical anxiety and low mathematical confidence. Here, we present a theoretical framework that investigates linkages between student engagement, mathematical anxiety, mathematical confidence, student achievement and subject mastery. We implement this framework in a large, first-year interdisciplinary science subject and monitor its impact over several years from 2010 to 2015. The implementation of the framework coincided with an easing of anxiety and enhanced confidence, as well as higher student satisfaction, retention and achievement. The framework offers interdisciplinary science educators greater flexibility and confidence in their approach to designing and delivering subjects that rely on mathematical concepts and practices. 相似文献

Computational Modeling of Organizations Comes of Age 总被引:2,自引:1,他引:1

As they are maturing—i.e., as they are becoming validated, calibrated and refined—computational emulation models of organizations are evolving into: powerful new kinds of organizational design tools for predicting and mitigating organizational risks; and flexible new kinds of organizational theorem-provers for validating extant organization theory and developing new theory. Over the past 50 years, computational modeling and simulation have had enormous impacts on the rate of advancement of knowledge in fields like physics, chemistry and, more recently, biology; and their subsequent application has enabled whole new areas of engineering practice. In the same way, as our young discipline comes of age, computational organizational models are beginning to impact behavioral, organizational and economic science, and management consulting practice. This paper attempts to draw parallels between computational modeling in natural sciences and computational modeling of organizations as a contributor to both social science and management practice.To illustrate the lifecycle of a computational organizational model that is now relatively mature, this paper traces the evolution of the Virtual Design Team (VDT) computational modeling and simulation research project at Stanford University from its origins in 1988 to the present. It lays out the steps in the process of validating VDT as a computational emulation model of organizations to the point that VDT began to influence management practice and, subsequently, to advance organizational science. We discuss alternate research trajectories that can be taken by computational and mathematical modelers who prefer the typical natural science validation trajectory—i.e., who attempt to impact organizational science first and, perhaps subsequently, to impact management practice.The paper concludes with a discussion of the current state-of-the-art of computational modeling of organizations and some thoughts about where, and how rapidly, the field is headed. 相似文献

This is a comprehensive study, that, by means of an empirical assessment of the DSS literature, systematically identifies the DSS reference disciplines and traces how concepts and findings by researchers in the contributing disciplines have been picked up by DSS researchers to be applied, extended, and refined in the development of DSS research subspecialties. Cluster analysis was employed to an author cocitation frequency matrix derived from a comprehensive database of the DSS literature over the period of 1970 through 1993. Twelve clusters were uncovered consisting of six major areas of DSS research (group DSS, foundations, model management, user interfaces, implementation, and multiple criteria DSS) and six contributing disciplines (multiple criteria decision making, cognitive science, organization science, artificial intelligence, group decision making, and systems science). 相似文献

The generation and processing of research data for modeling and simulation is an important part of the scientific work at WIAS. Together with scientific software it plays an essential role for the transfer of mathematical research results to industry or to other scientific disciplines. In the face of the emerging digital science agenda research data is now more and more recognized as an essential foundation for scientific work. The importance of research data is also emphasized by the recent adoption of the “DFG Guidelines on the Handling of Research Data” by the Deutsche Forschungsgemeinschaft and the Open Data Pilot within the EU Horizon 2020 programme. In this contribution we present our definition of research data in mathematical modeling and simulation and requirements for its management. (© 2016 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim) 相似文献

Mathematical modeling and computer simulations of brain creativity & consciousness, artificial intelligence, mathematical imaging are the areas of research where the networks of interconnected oscillators playing an important role. Here we are presenting novel approach for mathematical modeling of brain creativity in a form of 2D symmetrical colored artistic patterns (ornaments) and 3D patterning. It was shown that special networks of chaotic oscillators simulated by the difference equations (discrete logistic equation, Henon equations and discrete chemical reactions basic equations [1]) possess creative patterns within their chaotic regimes.

在大数据和人工智能时代,建立能够有效处理复杂数据的模型和算法,以从数据中获取有用的信息和知识是应用数学、统计学和计算机科学面临的共同难题.为复杂数据建立生成模型并依据这些模型进行分析和推断是解决上述难题的一种有效手段.从一种宏观的视角来看,无论是应用数学中常用的微分方程和动力系统,或是统计学中表现为概率分布的统计模型,还是机器学习领域兴起的生成对抗网络和变分自编码器,都可以看作是一种广义的生成模型.随着所处理的数据规模越来越大,结构越来越复杂,在实际问题中所需要的生成模型也变得也越来越复杂,对这些生成模型的数学结构进行精确地解析刻画变得越来越困难.如何对没有精确解析形式(或其解析形式的精确计算非常困难)的生成模型进行有效的分析和推断,逐渐成为一个十分重要的问题.起源于Bayes统计推断,近似Bayes计算是一种可以免于计算似然函数的统计推断技术,近年来在复杂统计模型和生成模型的分析和推断中发挥了重要作用.该文从经典的近似Bayes计算方法出发,对近似Bayes计算方法的前沿研究进展进行了系统的综述,并对近似Bayes计算方法在复杂数据处理中的应用前景及其和前沿人工智能方法的深刻联系进行了分析和讨论. 相似文献
