Perhaps you should try some spelling variations:
"modified objective evolutionary algorithm" » "modified objective evolution algorithm", "modified objective solution algorithm"
"machines learning method algorithm" » "machine learning method algorithm", "active learning method algorithm", "mapping learning method algorithm", "machines learning mom algorithm", "machines learning methods algorithm", "machines graining methods algorithm", "machines learning emotion algorithm"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective evolutionary algorithm") or ("machines learning method algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective evolutionary algorithm") OR ("machines learning method algorithm")).
• Removing quotes may allow a broader search: (( modified objective evolutionary algorithm ) or ( machines learning method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective evolutionary algorithm") or ("machines learning method algorithm"))*.
