Perhaps you should try some spelling variations:
"modified objective evolution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective solution algorithm", "modified objective convolution algorithms"
"machines learning methods algorithm" » "machine learning methods algorithm", "active learning methods algorithm", "mapping learning methods algorithm", "machines nursing 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 objective evolution algorithm\") OR (\"machines learning methods algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective evolution algorithm ) OR ( machines learning methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective evolution algorithm") OR ("machines learning methods algorithm"))*.
