Abstract

The hybrid conjugate gradient (CG) method is among the efficient variants of CG method for solving optimization problems. This is due to their low memory requirements and nice convergence properties. In this paper, we present an efficient hybrid CG method for solving unconstrained optimization models and show that the method satisfies the sufficient descent condition. The global convergence prove of the proposed method would be established under inexact line search. Application of the proposed method to the famous statistical regression model describing the global outbreak of the novel COVID-19 is presented. The study parameterized the model using the weekly increase/decrease of recorded cases from December 30, 2019 to March 30, 2020. Preliminary numerical results on some unconstrained optimization problems show that the proposed method is efficient and promising. Furthermore, the proposed method produced a good regression equation for COVID-19 confirmed cases globally.

Abstract

The focus of this research is the lack of provision of accessibility and public facilities specifically designed for persons with disabilities that aim to facilitate their activities outside the home. This gap can occur due to the lack of implementation of the NTB Regional Government Regulation No. 4 of 2019 concerning the protection and fulfillment of the rights of persons with disabilities. This study is also to find out the efforts of the village-level government in providing services to persons with disabilities in the form of assistance for accessibility of public services and individual services. This study uses a qualitative approach with the type of phenomenology. In obtaining data, this researcher used observation, interview, and documentation techniques. This research was conducted in Mujur Village, East Praya District, Central Lombok Regency. Based on the results of the research that has been done, it can be concluded that the implementation of policies from the NTB Regional Government Regulations that have been established by the NTB Provincial Government has not been implemented properly and evenly. Therefore, it is recommended that the local government, especially the Central Lombok Regency Government and the Mujur Village government, make efforts to provide adequate facilities for persons with disabilities.
