Perhaps you should try some spelling variations:
"modified affects digitization algorithms" » "modified affects optimization algorithms", "modified affects estimation algorithms", "modified effects digitization algorithms", "modified affect digitization algorithms", "modified affected digitization algorithms"
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"

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

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