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