Perhaps you should try some spelling variations:
"modified write optimization algorithmsss" » "modified write optimization algorithms", "modified write optimisation algorithm", "modified write estimation algorithms", "modified game optimization algorithmsss", "modified qoe optimization algorithmsss", "modified stage optimization algorithmsss"
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation algorithm"

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 optimization algorithmsss\") OR (\"modified objective estimation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified write optimization algorithmsss ) OR ( modified objective estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified write optimization algorithmsss") OR ("modified objective estimation algorithm"))*.
