Perhaps you should try some spelling variations:
"parameters estimation algorithmss" » "parameters estimation algorithm", "parameters optimization algorithms", "parameter estimation algorithmss", "parameter estimates algorithmss", "parameter optimization algorithmss", "parameters estimation algorithms", "parameters optimization algorithmss", "parameters optimisation algorithms"
"allocation estimation algorithms" » "allocation optimization algorithms", "motion estimation algorithms", "allocation estimation algorithm", "allocation optimisation algorithm"

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

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