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