Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"enabling nursing method algorithm" » "enabling learning method algorithm", "enabling nursing mom algorithm", "enabling nursing methods 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: (("enabling nursing method algorithm") OR ("modified multiobjective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( enabling nursing method algorithm ) or ( modified multiobjective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("enabling nursing method algorithm") or ("modified multiobjective optimisation algorithm"))*.
