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