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