Perhaps you should try some spelling variations:
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"
"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"

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