Geometric efficiency
WebApr 10, 2024 · The geometric iterative method (GIM) is widely used in data interpolation/fitting, but its slow convergence affects the computational efficiency. Recently, much work was done to guarantee the acceleration of GIM in the literature. In this work, we aim to further accelerate the rate of convergence by introducing a preconditioning … WebCalculate the efficiency curve for each geometry. How do they compare? Do they demonstrate that efficiency is proportional to the inverse of the distance squared? Gamma-Ray Efficiency Calibration
