Perhaps you should try some spelling variations:
"modified parameters estimation algorithms" » "modified parameter estimation algorithms", "modified parameter estimates algorithms", "modified parameter optimization algorithms", "modified parameters estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm"
"modified pose estimation algorithms" » "modified pose estimation algorithm", "modified pose optimization algorithms", "modified pose optimisation algorithm", "modified male estimation algorithms", "modified passive estimation 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 parameters estimation algorithms") OR ("modified pose estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified parameters estimation algorithms ) or ( modified pose estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameters estimation algorithms") or ("modified pose estimation algorithms"))*.
