Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified dilated convolution algorithm" » "modified dilated convolution algorithms", "modified dilated evolution algorithm", "modified dilated 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 multiobjective estimation algorithm") OR ("modified dilated convolution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective estimation algorithm\") OR (\"modified dilated convolution algorithm\"))*".
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) OR ( modified dilated convolution algorithm ))*.
