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