Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified write estimation algorithms" » "modified write optimization algorithms", "modified write optimisation algorithm", "modified write approximation algorithms", "modified risk estimation algorithms", "modified pose 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 write estimation algorithms") or ("modified multiobjective estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified write estimation algorithms") OR ("modified multiobjective estimation algorithm"))*.
• Removing quotes may allow a broader search: (( modified write estimation algorithms ) or ( modified multiobjective estimation algorithm ))*.
