Perhaps you should try some spelling variations:
"modified bi1 optimization algorithms" » "modified bi1 optimisation algorithm", "modified bi1 estimation algorithms", "modified bi1 estimation algorithm", "modified _ optimization algorithms", "modified qoe optimization algorithms", "modified game optimization algorithms"
"modified objective optimized algorithms" » "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimal algorithms", "modified objective optimization algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimized algorithms") OR ("modified bi1 optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective optimized algorithms ) or ( modified bi1 optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimized algorithms") or ("modified bi1 optimization algorithms"))*.
