<!-- ## Quasi Random Search

QuasiRandom sampling ensures a much more uniform exploration of the search space than traditional pseudo random. Thus, quasi random sampling is preferable when not all variables are discrete, the number of dimensions is high and the time required to evaluate a solution is high.

Algorithm name in katib is `chocolate-quasirandom`. -->

<!-- ## CMAES

CMAES search is one of the most powerful black-box optimization algorithm. However, it requires a significant number of model evaluation (in the order of 10 to 50 times the number of dimensions) to converge to an optimal solution. This search method is more suitable when the time required for a model evaluation is relatively low.
