Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"more learning method algorithm" » "more learning mom algorithm", "more learning methods algorithm", "more graining methods algorithm", "more learning emotion algorithm", "mobile learning method algorithm", "how learning 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: "((\"more learning method algorithm\") OR (\"modified multiobjective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( more learning method algorithm ) OR ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("more learning method algorithm") OR ("modified multiobjective optimization algorithm"))*.
