Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"
"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 objective optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified deep solution algorithm\") OR (\"modified objective optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified deep solution algorithm ) OR ( modified objective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified deep solution algorithm") OR ("modified objective optimization algorithms"))*.
