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