A Sampling-Based Method to Estimate the Volume of Solution Space for Linear Arithmetic Constraints

引用

Journal of Systems Science & Complexity 2024年

作者： xie yan-Feng YUAN Chun-Ming JING Rui-Juan KLMM Academy of Mathematics and Systems Science Chinese Academy of Sciences School of Mathematical Sciences University of Chinese Academy of Sciences School of Mathematical Sciences Jiangsu University

The linear arithmetic constraints play important roles in many research fields. Estimating the volume of their solution spaces has specific applications, such as programming verification, linear programming, polyhedral optimization, and so on. In this paper, the authors provide an efficient estimation for the volume of the solution space for linear arithmetic constraints. This method sums up the estimations for volumes of oblique cones centered along randomly generated rays. The error analysis is provided to improve the accuracy.

对句既是语言现象,也是艺术形式,其发展具有重要的诗史意义。汉语独特的韵律特点、语法特征、词义系统促进了对句的生成,五言诗的句子节奏特点则决定了它与对句的密切联动。汉魏至齐梁是诗歌对句发展的关键时期,它经历了“正一反一合”的历程。从古诗到颜延之,对句的语法严谨度和语义自由度成反比发展且波动剧烈。从颜延之、谢灵运开始,对句的语法严谨度和语义自由度成正比发展,实现了辩证统一。诗人不断调适对句并借此推动诗歌内容创新和形式创新,对句发展因此成为古典诗歌创新发展的重要原动力。对句的发展轨迹与规律,不仅体现中国文学的民族特色,更体现中国思想的民族智慧。

以588名4~5年级农村儿童为研究对象,采用多项式回归与响应面分析探讨母亲温暖和父亲温暖教养的一致性对农村儿童亲社会行为的影响,并考察心理资本在其中的作用。结果发现:(1)父母温暖教养一致时,父母温暖水平越高,农村儿童亲社会行为水平越高;(2)父母温暖教养不一致时,相较于父母温暖中等的儿童,高父亲温暖或高母亲温暖的儿童亲社会行为较高;(3)心理资本在父母温暖教养与农村儿童亲社会行为之间起部分中介作用。研究结果为农村儿童家庭教育及亲社会行为的干预提供新视角,对促进农村儿童积极适应具有重要的启示意义。

对《资本论》生态思想的科学研究,首先在于确定其研究对象。《资本论》的生态思想围绕着人与自然之间物质变换关系的批判展开,是对在资本主义生产方式占统治地位的社会中人与自然的物质变换关系、过程及其结果批判的统一。《资本论》的生态思想基于对人类社会和自然界运动发展规律的认识,通过对人与自然界辩证统一关系的规律性把握,聚焦劳动者创造财富、劳动者主体性的彰显以及为劳动者利益而斗争等问题,意图在批判的基础上通过斗争实践打破资本逻辑的制度规定,具有鲜明的科学性、人民性和实践性特征。《资本论》的生态思想通过资本逻辑批判的独特视角将对人与自然的认识推进到资本主义社会现实的历史中,揭露了作为历史发展动力的资本文明的文明暴行,蕴含着实现人与自然和谐共生的新文明趋向,对新时代中国生态文明建设具有重要的启迪意义。
