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