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

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 algorithmss") OR ("parameters optimization algorithms"))~.
• Removing quotes may allow a broader search: (( dung optimization algorithmss ) or ( parameters optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("dung optimization algorithmss") or ("parameters optimization algorithms"))*.
