Closure System and Its Semantics

open access: yesAxioms, 2021
It is well known that topological spaces are axiomatically characterized by the topological closure operator satisfying the Kuratowski Closure Axioms. Equivalently, they can be axiomatized by other set operators encoding primitive semantics of topology ...

Applications of pre-open sets

open access: yesApplied General Topology, 2008
Using the concept of pre-open set, we introduce and study topological properties of pre-limit points, pre-derived sets, preinterior and pre-closure of a set, pre-interior points, pre-border, prefrontier and pre-exterior. The relations between pre-derived

Stakeholder Perspectives on Energy Auctions: A Case Study in Roraima, Brazil

open access: yesEnergies, 2023
Energy auctions are commonly used to contract energy projects and are extensively studied from the regulator’s perspective. However, analyzing auctions from the stakeholders’ perspective is critical to determine the impact of regulatory details on the ...

On the relationship of interior-point methods

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1993
In this paper, we show that the moving directions of the primal-affine scaling method (with logarithmic barrier function), the dual-affine scaling method (with logarithmic barrier function), and the primal-dual interior point method are merely the Newton

An Algorithm Based on the Modified Sufficient Conditions of the Inertia-Controlling Method for the Global Solution of a General Quadratic Problem

open access: yesAppliedMath
In this paper, we consider a general quadratic problem (P) with linear constraints that are not necessarily linear independent. To resolve this problem, we use a new algorithm based on the Inertia-Controlling method while replacing the condition of the ...

Point Cloud vs. Mesh Features for Building Interior Classification

open access: yesRemote Sensing, 2020
Interpreting 3D point cloud data of the interior and exterior of buildings is essential for automated navigation, interaction and 3D reconstruction. However, the direct exploitation of the geometry is challenging due to inherent obstacles such as noise ...

Interior point algorithm for solving farm resource allocation problem

open access: yesApstract: Applied Studies in Agribusiness and Commerce, 2017
This paper introduces interior point algorithm as an alternative approach to simplex algorithm for solving farm resource allocation problem. The empirical result of interior point algorithm is compared with that of the simplex algorithm.

Interior Point Algorithm for Multi-UAVs Formation Autonomous Reconfiguration

open access: yesJournal of Control Science and Engineering, 2016
Here the problem of designing multi-UAVs formation autonomous reconfiguration is considered. Combined with three kinds of cost functions, nonlinear dynamic equations, and four inequality constraints, one nonlinear multiobjective optimization problem is ...

Structure-Exploiting Interior Point Methods [PDF]

open access: yes, 2020
Interior point methods are among the most popular techniques for large scale nonlinear optimization, owing to their intrinsic ability of scaling to arbitrary large problem sizes. Their efficiency has attracted in recent years a lot of attention due to increasing demand for large scale optimization in industry and engineering.
