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 $${\displaystyle f:\mathbb {R} ^{n}\to \mathbb {R} }$$. The other approach is trust region. The line search approach first finds a descent … 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. The interval is then divided by … Se mer • Dennis, J. E., Jr.; Schnabel, Robert B. (1983). "Globally Convergent Modifications of Newton's Method".
