Perhaps you should try some spelling variations:
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"
"modified df solutions algorithm" » "modified df solution algorithm", "modified df evolution algorithm", "modified df evolutionary algorithm", "modified _ solutions algorithm", "modified up solutions algorithm", "modified _ solution algorithm", "modified adam solutions algorithm", "modified bi1 solutions 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 df solutions algorithm") OR ("modified objective allocation algorithm"))~.
• Removing quotes may allow a broader search: (( modified df solutions algorithm ) or ( modified objective allocation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified df solutions algorithm") or ("modified objective allocation algorithm"))*.
