Perhaps you should try some spelling variations:
"modified passive optimization algorithms" » "modified passive optimisation algorithm", "modified passive estimation algorithm", "modified passive optimized algorithms", "modified bayesian optimization algorithms", "modified game optimization algorithms", "modified policy optimization algorithms", "modified adaptive optimization 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 passive optimization algorithms") OR ("modified quantile estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified passive optimization algorithms\") OR (\"modified quantile estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified passive optimization algorithms ) OR ( modified quantile estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified passive optimization algorithms") OR ("modified quantile estimation algorithms"))*.
