Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"how learning method algorithm" » "how learning mom algorithm", "how learning methods algorithm", "how graining methods algorithm", "how learning emotion algorithm", "shot learning method algorithm", "when learning method algorithm", "_ learning method algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective optimization algorithms") OR ("how learning method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithms\") OR (\"how learning method algorithm\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithms ) OR ( how learning method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithms") OR ("how learning method algorithm"))*.
