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