Perhaps you should try some spelling variations:
"parameters optimization algorithmssss" » "parameters optimisation algorithm", "parameters optimisation algorithmsss", "parameters estimation algorithmssss", "parameters estimation algorithmsss", "parameter optimization algorithmssss", "parameter estimation algorithmssss"
"dung optimization algorithms" » "dung optimisation algorithm", "dung estimation algorithms", "dung estimation algorithm", "stage optimization algorithms", "_ optimization algorithms", "game optimization algorithms"

You may be able to get more results by adjusting your search query.

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