Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified adam optimization algorithm" » "modified adam optimization algorithms", "modified adam optimisation algorithm", "modified adam estimation algorithm", "modified game optimization algorithm", "modified stage optimization algorithm", "modified _ optimization algorithm", "modified df optimization algorithm", "modified near optimization algorithm"

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 adam optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithm\") OR (\"modified adam optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) OR ( modified adam optimization algorithm ))*.
