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