Perhaps you should try some spelling variations:
"modified allocation optimization algorithm" » "modified allocation optimization algorithms", "modified allocation optimisation algorithm", "modified allocation estimation algorithm", "modified location optimization algorithm"
"modified quantile estimation algorithms" » "modified quantile estimation algorithm", "modified quantile optimization algorithms", "modified quantile optimisation algorithm", "modified adaptive estimation 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 allocation optimization algorithm\") OR (\"modified quantile estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified allocation optimization algorithm ) OR ( modified quantile estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimization algorithm") OR ("modified quantile estimation algorithms"))*.
