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