Perhaps you should try some spelling variations:
"modified quantile estimation algorithmsss" » "modified quantile estimation algorithms", "modified quantile estimation algorithm", "modified adaptive estimation algorithmsss"
"modified bayesian optimisation algorithm" » "modified bayesian optimization algorithms", "modified bayesian estimation algorithm", "modified bayesian estimation algorithms", "modified bayesian optimization algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified bayesian optimisation algorithm") or ("modified quantile estimation algorithmsss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimisation algorithm") OR ("modified quantile estimation algorithmsss")).
• Removing quotes may allow a broader search: (( modified bayesian optimisation algorithm ) or ( modified quantile estimation algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimisation algorithm") or ("modified quantile estimation algorithmsss"))*.
