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