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"
"modified male approximation algorithms" » "modified one approximation algorithms", "modified time approximation algorithms", "modified _ approximation algorithms"

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 male approximation algorithms\") OR (\"modified multiobjective optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified male approximation algorithms ) OR ( modified multiobjective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified male approximation algorithms") OR ("modified multiobjective optimisation algorithm"))*.
