Perhaps you should try some spelling variations:
"write optimization algorithmssssssssssssss" » "write optimization algorithmsssssssssssssss", "write optimisation algorithmssssssssssssss", "write estimation algorithmssssssssssssss", "game optimization algorithmssssssssssssss", "qoe optimization algorithmssssssssssssss", "stage optimization algorithmssssssssssssss"
"parameter optimization algorithm" » "parameter optimization algorithms", "parameter optimisation algorithm", "parameter estimation algorithm", "parameters optimization algorithm"

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