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