Perhaps you should try some spelling variations:
"modified total estimation algorithms" » "modified total optimization algorithms", "modified total optimisation algorithm", "modified total approximation algorithms", "modified motion estimation algorithms", "modified pose estimation algorithms", "modified total variation algorithms", "modified thermal estimation algorithms", "modified ti6al4v estimation algorithms"
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation algorithm"

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 total estimation algorithms") OR ("modified objective estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified total estimation algorithms ) or ( modified objective estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified total estimation algorithms") or ("modified objective estimation algorithm"))*.
