Perhaps you should try some spelling variations:
"allocation estimation algorithmssss" » "allocation estimation algorithm", "allocation estimation algorithmsss", "allocation optimization algorithmssss", "allocation optimisation algorithmsss", "motion estimation algorithmssss"
"parameters estimation algorithms" » "parameter estimation algorithms", "parameter estimates algorithms", "parameter optimization algorithms", "parameters estimation algorithm", "parameters optimization algorithms", "parameters 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: "((\"parameters estimation algorithms\") OR (\"allocation estimation algorithmssss\"))~".
• Removing quotes may allow a broader search: (( parameters estimation algorithms ) OR ( allocation estimation algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("parameters estimation algorithms") OR ("allocation estimation algorithmssss"))*.
