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

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 allocation algorithm\") OR (\"modified quantile estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified objective allocation algorithm ) OR ( modified quantile estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective allocation algorithm") OR ("modified quantile estimation algorithms"))*.
