Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"code nursing methods algorithm" » "code using methods algorithm", "care nursing methods algorithm", "models nursing methods algorithm", "code nursing method algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("code nursing methods algorithm") OR ("modified multiobjective estimation algorithms"))~.
• Removing quotes may allow a broader search: (( code nursing methods algorithm ) or ( modified multiobjective estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("code nursing methods algorithm") or ("modified multiobjective estimation algorithms"))*.
