Perhaps you should try some spelling variations:
"modified passive optimization algorithmss" » "modified passive optimization algorithms", "modified passive optimisation algorithm", "modified passive estimation algorithm", "modified bayesian optimization algorithmss", "modified game optimization algorithmss", "modified policy optimization algorithmss", "modified adaptive optimization algorithmss"
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation 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 passive optimization algorithmss") OR ("modified objective estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified passive optimization algorithmss\") OR (\"modified objective estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified passive optimization algorithmss ) OR ( modified objective estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified passive optimization algorithmss") OR ("modified objective estimation algorithms"))*.
