Perhaps you should try some spelling variations:
"modified policy estimation algorithmssss" » "modified policy estimation algorithms", "modified policy estimation algorithm", "modified policy optimization algorithmssss", "modified pose estimation algorithmssss", "modified motion estimation algorithmssss"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"

Try widening your search to All Fields.

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