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