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