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

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