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