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