Perhaps you should try some spelling variations:
"parameter optimization algorithm" » "parameter optimization algorithms", "parameter optimisation algorithm", "parameter estimation algorithm", "parameters optimization algorithm"
"allocation estimation algorithmssssssssssssssssss" » "allocation optimization algorithmssssssssssssssssss", "motion estimation algorithmssssssssssssssssss"

Try widening your search to All Fields.

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