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

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

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