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"

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