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