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 algorithmssssssss" » "write optimisation algorithmsssssss", "write estimation algorithmssssssss", "write estimation algorithmsssssss", "game optimization algorithmssssssss", "qoe optimization algorithmssssssss", "stage optimization algorithmssssssss"

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