Perhaps you should try some spelling variations:
"modified made optimized algorithms" » "modified made optimized algorithm", "modified made optimizer algorithms", "modified made optimization algorithms", "modified male optimized algorithms", "modified adam optimized algorithms", "modified df 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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective predation algorithm") OR ("modified made optimized algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective predation algorithm ) or ( modified made optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective predation algorithm") or ("modified made optimized algorithms"))*.
