The penalty method is a popular method for solving constrained optimization problems,which can change the constrained optimization to the unconstrained optimization.With the integral-level set method,a new approach was proposed,which i sbriefer than the penalty method,to achivev the unconstrained optimization and a nonlinear equality.By studying the properties of the function.a level-value estimate algorithm and an implementation algorithm were given by means of the uniform distribution of the good point set. 相似文献

传统的遗传算法在求解带约束的数值优化问题时,主要采用罚函数法。文章针对罚函数法在实际应用中的不足,提出了一种将约束优化问题转化为双目标优化问题,然后使用双目标遗传算法进行求解的方法。仿真结果表明该方法是一种有效的约束问题寻优方法。 相似文献

借鉴罚函数法思想,将建立在Gauss网络的单变量边缘分布算法应用于非线性约束优化问题,提出的新算法突破了传统基于约束保持法或可行规则法的约束处理.且单变量边缘分布是基于搜索空间的宏观层面的进化方法,具备更强的全局搜索能力和更高的收敛率,从而为约束问题的求解提供了一种新的途径. 相似文献

量刑建议制度是检察机关有效制约法官量刑裁量权,加强刑事审判法律检察监督和保护受害人的重要保障。我国最高人民检察院、最高人民法院的三个司法解释确立了量刑建议制度,但相关立法还存在问题。因此,为保障量刑建议制度功效发挥,我国应针对问题而完善相关立法。 相似文献

死刑是剥夺犯罪分子生命的刑罚方法,死刑的执行方式是死刑制度的重要组成部分。在人类社会历史进程中,死刑执行方式无不打上了时代的烙印。死刑的执行方式经历了从野蛮、残酷到人道、文明的转变。随着人类文明和科学技术的发展,死刑执行方法逐步趋向人道。我国刑事诉讼法明确地把“注射”纳入死刑执行方式之中,这标志着我国死刑执行制度正在不断地向人道化、文明化的方向发展。将死刑的执行方式作为切入点,以探寻完善我国的死刑执行制度之路径。 相似文献

文[6]中，我们对非线性混合整数规划的解法进行了探讨，利用罚函数把有约束非线性混合整数规划问题化为等价的无约束非线性混合整数规划问题，然后把离散整变量连续化，从而非线性混合整数规划化为与之等价的无约束非线性规划。本文弱化了文[6]中定理1的条件，并得到了相应的结论。 相似文献

针对大型复杂的空间桁架结构的大位移静力分析,提出一个新的几何非线性求解格式。该格式基于有限元法,采用节点位置而不是节点位移来描述问题。应用固定空间的笛卡尔坐标系,从提出的位置概念直接确定应变。将该求解格式算例结果与弧长法计算结果比较,结果表明,该求解格式具有良好的精度,对大型复杂空间桁架结构的几何非线性分析是可行和有效的。 相似文献

This paper explores the reflections of practising educational psychologists on the usefulness of a framework used in training for the role of educational psychologist. The Monsen problem‐solving framework is taught on the M.Sc. Educational Psychology Programme at Strathclyde University. The framework aims to support learning in the processes of conceptualising complex and ill‐defined problems and in subsequently developing effective interventions. It offers systematic steps to help structure, organise and analyse the complexities of problems in a coherent way, facilitating understanding and transparency of processes for both psychologists and clients. How effective is the training device in ensuring that problems are understood and addressed in practice? Does the framework influence or shape the work of the fully‐fledged practitioner? The present study indicates that the Monsen framework is perceived to be highly effective in some executive areas and that these aspects transfer well to applied practice. However there is less transferability in those aspects relating more directly to psychological theory and thinking, in particular the formulation of hypotheses and the sharing of the problem dynamics with stakeholders. Respondents describe the limitations of the model in the contexts of collaborative working, time management and competing theories and frameworks. These issues are discussed in relation to professional practice and accountability. It is proposed that the advantages of using the Monsen model may be even clearer if the role of psychological theory is more fully articulated within the framework. 相似文献

刑罚目的在刑罚理论中居于核心地位,它对于刑罚的创制与适用有着直接的指导意义。西方的刑罚目的理论源远流长,大致可以分为报应刑论、目的刑论、折中刑论。我国关于刑罚目的的争论及评述较多,无论是公正惩罚的刑罚目的、预防犯罪的刑罚目的或保护包括犯罪人在内的全体公民的基本人权的刑罚目的,都有确立我国刑罚目的之借鉴之处,单独取任何一个作为刑罚目的都不够完全。我国应该有的刑罚目的是公正惩罚犯罪及预防犯罪,保护包括犯罪人在内的全体公民的基本人权。 相似文献

This paper deals with the economically optimized design and sensitivity of two of the most widely used systems in geotechnical
engineering: spread footing and retaining wall. Several recent advanced optimization methods have been developed, but very
few of these methods have been applied to geotechnical problems. The current research develops a modified particle swarm optimization
(MPSO) approach to obtain the optimum design of spread footing and retaining wall. The algorithm handles the problem-specific
constraints using a penalty function approach. The optimization procedure controls all geotechnical and structural design
constraints while reducing the overall cost of the structures. To verify the effectiveness and robustness of the proposed
algorithm, three case studies of spread footing and retaining wall are illustrated. Comparison of the results of the present
method, standard PSO, and other selected methods employed in previous studies shows the reliability and accuracy of the algorithm.
Moreover, the parametric performance is investigated in order to examine the effect of relevant variables on the optimum design
of the footing and the retaining structure utilizing the proposed method. 相似文献
