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