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