Checks whether the problem structure can give a line-search a hint.
function candoit = canGetLinesearch(problem)
This function calls:
This function is called by:
- barzilaiborwein Riemannian Barzilai-Borwein solver with non-monotone line-search.
- rlbfgs Riemannian limited memory BFGS solver for smooth objective functions.
- conjugategradient Conjugate gradient minimization algorithm for Manopt.
- linesearch_constant Forces a constant multiplier on the descent direction chosen by the algorithm.
- linesearch_hint Armijo line-search based on the line-search hint in the problem structure.
- steepestdescent Steepest descent (gradient descent) minimization algorithm for Manopt.
