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