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