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