Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"code nursing method algorithm" » "code nursing mom algorithm", "code nursing methods algorithm", "code using method algorithm", "care nursing method algorithm", "models nursing method 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 algorithm") or ("code nursing method algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimization algorithm") OR ("code nursing method algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) or ( code nursing method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") or ("code nursing method algorithm"))*.
