Perhaps you should try some spelling variations:
"parameters estimation algorithmssss" » "parameters estimation algorithm", "parameter estimation algorithmssss", "parameter estimates algorithmssss", "parameter optimization algorithmssss", "parameters estimation algorithmsss", "parameters optimization algorithmssss", "parameters optimisation algorithmsss"
"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 algorithmssss") OR ("allocation estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"parameters estimation algorithmssss\") OR (\"allocation estimation algorithms\"))".
• Removing quotes may allow a broader search: (( parameters estimation algorithmssss ) OR ( allocation estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("parameters estimation algorithmssss") OR ("allocation estimation algorithms"))*.
