Perhaps you should try some spelling variations:
"allocation estimation algorithmssssss" » "allocation estimation algorithm", "allocation optimization algorithmssssss", "motion estimation algorithmssssss", "allocation estimation algorithmsssss", "allocation optimisation algorithmsssss"
"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.

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