Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"
"mapping focusing method algorithm" » "mapping forecasting method algorithm", "nursing focusing method algorithm", "mapping focusing mom algorithm"

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

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