Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified over optimization algorithms" » "modified over optimisation algorithm", "modified over estimation algorithms", "modified over optimized algorithms", "modified qoe optimization algorithms", "modified _ optimization algorithms", "modified game optimization algorithms", "modified near optimization algorithms", "modified orca optimization 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 over optimization algorithms") or ("modified multiobjective estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified over optimization algorithms") OR ("modified multiobjective estimation algorithm")).
• Removing quotes may allow a broader search: (( modified over optimization algorithms ) or ( modified multiobjective estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified over optimization algorithms") or ("modified multiobjective estimation algorithm"))*.
