Perhaps you should try some spelling variations:
"modified objective optimizer algorithms" » "modified objective optimized algorithms", "modified objective optimized algorithm", "modified objective optimization algorithms", "modified objective optimal algorithms"
"modified trace solution algorithm" » "modified trace evolution algorithm", "modified trace convolution algorithms", "modified trace evolutionary algorithm", "modified traces solution algorithm", "modified male solution algorithm", "modified orca solution algorithm", "modified exact solution algorithm", "modified nacl 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 objective optimizer algorithms") OR ("modified trace solution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimizer algorithms\") OR (\"modified trace solution algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimizer algorithms ) OR ( modified trace solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimizer algorithms") OR ("modified trace solution algorithm"))*.
