Perhaps you should try some spelling variations:
"modified risk optimization algorithmss" » "modified risk optimization algorithms", "modified risk optimisation algorithm", "modified risk estimation algorithm", "modified robust optimization algorithmss", "modified _ optimization algorithmss", "modified game optimization algorithmss", "modified bi1 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 objective estimation algorithms") OR ("modified risk optimization algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective estimation algorithms\") OR (\"modified risk optimization algorithmss\"))".
• Removing quotes may allow a broader search: (( modified objective estimation algorithms ) OR ( modified risk optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithms") OR ("modified risk optimization algorithmss"))*.
