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