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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"allocation estimation algorithms\") OR (\"parameters estimation algorithmss\"))~".
• Removing quotes may allow a broader search: (( allocation estimation algorithms ) OR ( parameters estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("allocation estimation algorithms") OR ("parameters estimation algorithmss"))*.
