Perhaps you should try some spelling variations:
"write optimization algorithmssssss" » "write optimization algorithms", "write optimisation algorithm", "write optimization algorithmsssssss", "write optimisation algorithmssssss", "write estimation algorithmssssss", "game optimization algorithmssssss", "qoe optimization algorithmssssss", "stage optimization algorithmssssss"
"parameters optimization algorithm" » "parameter optimization algorithm", "parameter estimation algorithm", "parameters optimization algorithms", "parameters optimisation algorithm", "parameters estimation 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 algorithmssssss") or ("parameters optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("write optimization algorithmssssss") OR ("parameters optimization algorithm")).
• Removing quotes may allow a broader search: (( write optimization algorithmssssss ) or ( parameters optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("write optimization algorithmssssss") or ("parameters optimization algorithm"))*.
