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

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