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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"dung optimization algorithmss\") OR (\"parameters optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( dung optimization algorithmss ) OR ( parameters optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("dung optimization algorithmss") OR ("parameters optimization algorithm"))*.
