Wellhead choke is an integral part of production systems. Wellhead chokes act as regulators to protect surface facilities from high rate slugs, formation damage, and water coning. These chokes also    control the decline rate of reservoir p... see more

Contex. Making managerial decisions is often associated with solving one-dimensional global optimization problems. The most important property of global optimization methods is their speed, which is determined by the number of calls to the objective funct... see more

In this study, we deal with the nonlinear constrained global optimization problems. First, we introduce a new smooth exact penalty function for constrained optimization problems. We combine the exact penalty function with the auxiliary function in regard ... see more

In this paper we consider a bat algorithm for solving the problem of global optimization. This metaheuristic algorithm applies to swarm intelligence algorithms, which are developing rapidly in recent years. The aim of the work is to improve the bat algori... see more

In the presence of conducting inhomogeneities in near-surface structures, apparent resistivity data in magnetotelluric sounding can be severely distorted. This is due to electric fields generated from boundary charges on surficial inhomogeneities. Such di... see more

This paper searches for global optima for size optimization benchmarks utilizing a method based on branch and bound principles. The goal is to demonstrate the process for finding these global optima on the basis of two examples. A suitable parallelization... see more

The simulation of complex physics models may lead to enormous computer running times. Since the simulations are expensive it is necessary to exploit the computational budget in the best possible manner. If for a few input parameter settings an output data... see more

In this study, efficient global optimization (EGO) with a multi-fidelity hybrid surrogate model for multi-objective optimization is proposed to solve multi-objective real-world design problems. In the proposed approach, a design exploration is carried out... see more

The present research focuses on the study of the factors of sales optimization in a tobacco company. The reasons for undertaking this study were to identify and analyze the explanatory factors of the optimization of the sale in the commercial company in g... see more
