The new shape should be compatible with the original shape. If an integer, then the result will be a 1-D array of that length. One shape dimension can be -1. Witryna12 paź 2024 · Line search is an optimization algorithm for univariate or multivariate optimization. The algorithm requires an initial position in the search space and a direction along which to search. It will then choose the next position in the search space from the initial position that results in a better or best objective function evaluation.
