WebAug 31, 2024 · Running the conjugate gradient, the algorithm terminates in 5 steps. We examine the error in the residual by computing the sum of the absolute residual components. Note that this is not the error in the solution but rather the error in the system. We see that the error drops sharply at 4 iterations, and then again in the 5th iteration. … Webarticle “An Introduction to the Conjugate Gradient Method Without the Agonizing Pain”.

WebGenetic Algorithms (GA) are useful optimization methods for exploration of the search space, but they usually have slowness problems to exploit and converge to the minimum. On the other hand, gradient based methods converge faster to local minimums, although are not so robust (e.g., flat areas and discontinuities can cause problems) and they lack … http://www.ncts.ncku.edu.tw/phys/cmr/071123/cg.pdf
