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