Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithms"
"modified quadratic estimation algorithm" » "modified quadratic optimization algorithm", "modified quantile estimation algorithm"

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