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 … See more 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 $${\displaystyle f:\mathbb {R} ^{n}\to \mathbb {R} }$$. … See more • Golden section search • Grid search • Learning rate • Pattern search (optimization) See more 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.

WebThe line search algorithms seek to (approximately) minimize ’( ) for 0. 1.4.1 Exact Line Search In the exact sense, line search minimizes ’( ) for 0 or 2[0;s]. But this minimization can be expensive, and its accuracy is usually not critical.
