Perhaps you should try some spelling variations:
"modified over optimization algorithms" » "modified over optimisation algorithm", "modified over estimation algorithm", "modified over optimized algorithms", "modified qoe optimization algorithms", "modified _ optimization algorithms", "modified game optimization algorithms", "modified near optimization algorithms", "modified orca optimization algorithms"
"modified allocation estimation algorithms" » "modified allocation optimization algorithms", "modified motion estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimisation algorithm", "modified allocation approximation algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified allocation estimation algorithms") or ("modified over optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified allocation estimation algorithms") OR ("modified over optimization algorithms")).
• Removing quotes may allow a broader search: (( modified allocation estimation algorithms ) or ( modified over optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified allocation estimation algorithms") or ("modified over optimization algorithms"))*.
