Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"enabling nursing method algorithm\") OR (\"modified objective optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( enabling nursing method algorithm ) OR ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("enabling nursing method algorithm") OR ("modified objective optimisation algorithm"))*.
