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

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