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

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

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