Perhaps you should try some spelling variations:
"modified policy optimization algorithmssssss" » "modified policy optimization algorithms", "modified topology optimization algorithmssssss"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

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