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