Perhaps you should try some spelling variations:
"modified allocation optimization algorithmss" » "modified allocation optimization algorithms", "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified location optimization algorithmss"
"modified policy optimisation algorithm" » "modified policy optimization algorithms", "modified policy estimation algorithm", "modified policy estimation algorithms", "modified policy optimization algorithm", "modified topology optimization algorithm"

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 optimisation algorithm") OR ("modified allocation optimization algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified policy optimisation algorithm\") OR (\"modified allocation optimization algorithmss\"))".
• Removing quotes may allow a broader search: (( modified policy optimisation algorithm ) OR ( modified allocation optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified policy optimisation algorithm") OR ("modified allocation optimization algorithmss"))*.
