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