Perhaps you should try some spelling variations:
"modified trained convolution algorithms" » "modified trained evolution algorithm", "modified trained solution algorithm", "modified trained convolutional algorithms", "modified traces convolution algorithms"
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"

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 trained convolution algorithms\") OR (\"modified notion estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified trained convolution algorithms ) OR ( modified notion estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified trained convolution algorithms") OR ("modified notion estimation algorithms"))*.
