Perhaps you should try some spelling variations:
"modified model convolution algorithms" » "modified model evolution algorithm", "modified model solution algorithm", "modified male convolution algorithms"
"modified network estimation algorithms" » "modified network estimation algorithm", "modified network optimization algorithms", "modified network optimisation algorithm", "certified network estimation algorithms", "defined network estimation algorithms", "modified near estimation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified model convolution algorithms") OR ("modified network estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified model convolution algorithms\") OR (\"modified network estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified model convolution algorithms ) OR ( modified network estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified model convolution algorithms") OR ("modified network estimation algorithms"))*.
