Perhaps you should try some spelling variations:
"modified quantile optimization algorithms" » "modified quantile optimisation algorithm", "modified quantile estimation algorithm", "modified quantile optimized algorithms", "modified quantile estimation algorithms", "modified quadratic optimization algorithms", "modified static optimization algorithms", "modified adaptive optimization algorithms"
"modified df estimation algorithms" » "modified df estimation algorithm", "modified df optimisation algorithm", "modified df approximation algorithms", "modified _ estimation algorithms", "modified adam estimation algorithms", "modified bi1 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 df estimation algorithms") OR ("modified quantile optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified df estimation algorithms\") OR (\"modified quantile optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified df estimation algorithms ) OR ( modified quantile optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified df estimation algorithms") OR ("modified quantile optimization algorithms"))*.
