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"
"mapping nursing methods algorithm" » "impacting nursing methods algorithm", "mapping learning methods algorithm", "mapping nursing method 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: "((\"modified multiobjective optimisation algorithm\") OR (\"mapping nursing methods algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) OR ( mapping nursing methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") OR ("mapping nursing methods algorithm"))*.
