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

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