Optimistic optimization oo
http://proceedings.mlr.press/v33/wang14d.pdf WebMar 23, 2024 · This package implements optimistic optimization methods [1,2,3] for global optimization of deterministic or stochastic functions. The algorithms feature guarantees of the convergence to a global optimum. They require minimal assumptions on the (only local) smoothness, where the smoothness parameter does not need to be known. They are …

WebIn this paper, we propose to adapt the recent advances in tree searches and partitioning techniques to design and analyze novel black-box combinatorial solvers. A first contribution is the analysis of a first tree-search algorithm called Optimistic Lipschitz Tree Search (OLTS) which assumes the Lipschitz constant of the function to be known ...

WebSep 15, 2013 · The symmetrization of the search directions used in this paper is based on the Nesterov–Todd scaling scheme, and only full Nesterov–Todd step is used at each iteration. We derive the iteration bound that matches the currently best known iteration bound for small-update methods, namely, O ( r log r ε). WebOptimistic Optimization applied to Trees (POLY-HOOT ), provably converges to an arbitrarily small neighborhood of the optimum at a polynomial rate. Contributions. First, we enhance the continuous-armed bandit strategy HOO, and analyze its regret concentration rate in a non-stationary setting, which may also be of independent theoretical interest
