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