Perhaps you should try some spelling variations:
"modified quantile optimization algorithms" » "modified quantile optimisation algorithm", "modified quantile estimation algorithms", "modified quantile optimized algorithms", "modified quadratic optimization algorithms", "modified static optimization algorithms", "modified adaptive optimization algorithms"
"modified df estimation algorithm" » "modified _ estimation algorithm", "modified adam estimation algorithm", "modified bi1 estimation algorithm"

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 algorithm") OR ("modified quantile optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified df estimation algorithm\") OR (\"modified quantile optimization algorithms\"))*".
• Removing quotes may allow a broader search: (( modified df estimation algorithm ) OR ( modified quantile optimization algorithms ))*.
