Efficient hypergeometric wavelet approach for solving lane-emden equations
Nonlinear initial / boundary value problems present challenges in solving due to the divergence of coefficients near singular points. This study introduces a novel hypergeometric wavelet-based approach designed to effectively address these equations. The specialized wavelet method efficiently manages singularities, resulting in improved accuracy. To evaluate the precision and effectiveness of this approach, Lane-Emden type problems are solved using the proposed methodology and compared against established benchmarks. Comparative analyses with alternative wavelet methods are conducted, featuring absolute error tables and graphical representations. The findings highlight the exceptional accuracy and efficiency of the proposed method relative to existing approaches. An advantage of this method is its requirement of fewer basis functions, leading to reduced computational time and complexity.
期刊介绍:
Computational Science is a rapidly growing multi- and interdisciplinary field that uses advanced computing and data analysis to understand and solve complex problems. It has reached a level of predictive capability that now firmly complements the traditional pillars of experimentation and theory.
The recent advances in experimental techniques such as detectors, on-line sensor networks and high-resolution imaging techniques, have opened up new windows into physical and biological processes at many levels of detail. The resulting data explosion allows for detailed data driven modeling and simulation.
This new discipline in science combines computational thinking, modern computational methods, devices and collateral technologies to address problems far beyond the scope of traditional numerical methods.
Computational science typically unifies three distinct elements:
• Modeling, Algorithms and Simulations (e.g. numerical and non-numerical, discrete and continuous);
• Software developed to solve science (e.g., biological, physical, and social), engineering, medicine, and humanities problems;
• Computer and information science that develops and optimizes the advanced system hardware, software, networking, and data management components (e.g. problem solving environments).
