Perhaps you should try some spelling variations:
"modified risk estimation algorithms" » "modified risk estimation algorithm", "modified risk optimization algorithms", "modified risk optimisation algorithm", "modified pose estimation algorithms", "modified bi1 estimation algorithms"
"modified objective optimized algorithm" » "modified objective optimal algorithm", "modified objective optimization algorithm", "modified objective optimized algorithms", "modified objective optimizer algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimized algorithm") OR ("modified risk estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective optimized algorithm ) or ( modified risk estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimized algorithm") or ("modified risk estimation algorithms"))*.
