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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective estimation algorithms\") OR (\"modified quantile optimized algorithms\"))~".
• Removing quotes may allow a broader search: (( modified objective estimation algorithms ) OR ( modified quantile optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithms") OR ("modified quantile optimized algorithms"))*.
