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

Try widening your search to All Fields.

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

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