Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"mapping nursing method algorithm" » "mapping nursing mom algorithm", "impacting nursing method algorithm", "mapping learning method algorithm", "mapping nursing methods 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 multiobjective optimization algorithms") OR ("mapping nursing method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithms\") OR (\"mapping nursing method algorithm\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithms ) OR ( mapping nursing method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithms") OR ("mapping nursing method algorithm"))*.
