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