Added credits to the s∗ACM-ES algorithm. Section 1 Added references and clarified the motivation. Section 3 Added references. Abstract: The interest in accelerating black-box optimizers has resulted in several surrogate model-assisted version of the Covariance Matrix Adaptation Evolution Strategy, a state-of-the-art continuous black-box optimizer. The version called Surrogate CMA-ES uses Gaussi...

electronic government is a new concept that governments according to level of development implement in different ways. utilizing informational systems in business sections has created potential context for developing electronic government. customer relationship ‎management (crm) is an important system in management that helps to develop electronic government and promote citizenship-based in org...

BACKGROUND Before a new test is introduced in clinical practice, evidence is needed to demonstrate that its use will lead to improvements in patient health outcomes. Studies reporting test accuracy may not be sufficient, and clinical trials of tests that measure patient health outcomes are rarely feasible. Therefore, the consequences of testing on patient management are often investigated as an...

It has been shown that cooperative coevolution (CC) can effectively deal with large scale optimization problems (LSOPs) through a divide-and-conquer strategy. However, its performance is severely restricted by the current context-vectorbased sub-solution evaluation method since this method needs to access the original high dimensional simulation model when evaluating each sub-solution and thus ...

Surrogate constraint methods have been embedded in a variety of mathematical programming applications over the past thirty years, yet their potential uses and underlying principles remain incompletely understood by a large segment of the optimization community. In a number of significant domains of combinatorial optimization, researchers have produced solution strategies without recognizing tha...

background: using the method “surrogacy” in which a woman accepts to bear and deliver a child for a married couple is considered as a subsidiary method in infertility therapy. this method is relatively new in iran. objective: the purpose of this study was to evaluate the experiences of the women involved in surrogacy and to reveal some issues related to this method. materials and methods: the m...

In both numerical and stochastic optimization methods, surrogate models are often employed in lieu of the expensive high-fidelity models to enhance search efficiency. In gradient-based numerical methods, the trustworthiness of the surrogate models in predicting the fitness improvement is often addressed using ad hoc move limits or a trust region framework (TRF). Inspired by the success of TRF i...

this study intends to propose a modern model in the field of human resources (hr) strategic management through designing human resources’ competence framework. based on this strategic orientation of organization on human resources management system has been investigated considering the mediating role of competence approach in central bank of the islamic republic of iran. in order to implement a...
