Gradient intersection method
WebOct 17, 2016 · The intersection of the two planes is a line (if the gradients are not colinear). Since the intersection belongs to each of the tangent planes, it is perpendicular to both gradients. So now you have two vectors and you want to … WebJan 1, 1973 · Line search methods for proximal gradient-type methods Line search methods for gradient-type algorithms date several decades ago [7,14, 25, 26].

WebMay 14, 2024 · The gradient projection method is generalized to the case of nonconvex sets of constraints representing the set-theoretic intersection of a smooth surface with a convex closed set. Necessary optimality conditions are studied, and the convergence of the method is analyzed. INTRODUCTION WebDec 1, 2024 · The gradient intersection method uses the pressure profile along the pipeline to localize the leak. The pressure drop for a horizontal line without any elevation is linear as such if a leak occurs, the flow before the leak site increases and decreases after. This results in an increase in the pressure drop before the leak and decreases after ...
