Perhaps you should try some spelling variations:
"modified objective optimized algorithm" » "modified objective optimal algorithm", "modified objective optimization algorithm", "modified objective optimized algorithms", "modified objective optimizer algorithms"
"modified global variation algorithm" » "modified global estimation algorithm", "modified global predation algorithm", "modified global estimation algorithms", "modified total variation algorithm", "modified global edition 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 optimized algorithm") OR ("modified global variation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimized algorithm\") OR (\"modified global variation algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimized algorithm ) OR ( modified global variation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimized algorithm") OR ("modified global variation algorithm"))*.
