Perhaps you should try some spelling variations:
"modified objective optimization algorithmss" » "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective optimization algorithmsss", "modified objective optimisation algorithmss", "modified objective estimation algorithmss", "modified multiobjective optimization algorithmss"
"modified policy optimization algorithm" » "modified policy optimization algorithms", "modified policy optimisation algorithm", "modified policy estimation algorithm", "modified topology optimization 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 policy optimization algorithm") or ("modified objective optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified policy optimization algorithm") OR ("modified objective optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified policy optimization algorithm ) or ( modified objective optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified policy optimization algorithm") or ("modified objective optimization algorithmss"))*.
