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

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