Exploring the Applicability of Chaotic Maps in Artificial Hummingbird Algorithm: From Algorithm Construction to Case Verification

Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.
A research gap exists concerning how different chaotic mappings influence the applicability of metaheuristic algorithms, along with inherent limitations of the traditional artificial hummingbird algorithm (AHA). Specifically, blind spots in population coverage and vulnerability to local optima stemming from random initialization.

A higher order numerical method for transonic flows [PDF]

, 1997
This thesis presents and verifies a numerical method for solving the compressible Euler equations. The method is based on a finite volume method with an upwind type TVD dissipation terms originally developed by Harten ( 1983 ) for scalar hyperbolic ...

Efficient upwind algorithms for solution of the Euler and Navier-stokes equations [PDF]

, 1995
An efficient three-dimensionasl tructured solver for the Euler and Navier-Stokese quations is developed based on a finite volume upwind algorithm using Roe fluxes. Multigrid and optimal smoothing multi-stage time stepping accelerate convergence.

A spectral collocation method based on integrated Chebyshev polynomials for two-dimensional biharmonic boundary-value problems [PDF]

, 2007
This paper reports a new spectral collocation method for numerically solving two-dimensional biharmonic boundary-value problems. The construction of the Chebyshev approximations is based on integration rather than conventional differentiation.

Trajectory generation for autonomous unmanned aircraft using inverse dynamics [PDF]

, 2010
The problem addressed in this research is the in-flight generation of trajectories for autonomous unmanned aircraft, which requires a method of generating pseudo-optimal trajectories in near-real-time, on-board the aircraft, and without external ...
