The line search approach first finds a descent direction along which the objective function will be reduced and then computes a step size that determines how far should move along that direction. The descent direction can be computed by various methods, such as gradient descent or quasi-Newton method . Se mer In optimization, the line search strategy is one of two basic iterative approaches to find a local minimum $${\displaystyle \mathbf {x} ^{*}}$$ of an objective function $${\displaystyle f:\mathbb {R} ^{n}\to \mathbb {R} }$$. … Se mer • Golden section search • Grid search • Learning rate Se mer Direct search methods In this method, the minimum must first be bracketed, so the algorithm must identify points x1 and x2 such that the sought minimum lies between them.
