Perhaps you should try some spelling variations:
"modified parameters optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"modified pose estimation algorithmss" » "modified pose estimation algorithms", "modified pose estimation algorithm", "modified pose optimization algorithms", "modified male estimation algorithmss", "modified passive estimation algorithmss"

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 pose estimation algorithmss") OR ("modified parameters optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified pose estimation algorithmss ) or ( modified parameters optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified pose estimation algorithmss") or ("modified parameters optimisation algorithm"))*.
